Hi Robert,
This is caused by not having a steady hand.
By moving one's hand slightly which also moves the mouse and all the files
that are selected, Windows interprets this as dragging which copies the
files. Done this plenty of times myself. ;-)
You either have to practice or set the drag sensitivity differently.
Drag sensitivity specifies how far (in pixels) the mouse must
move with the button held down before the system decides
that you are dragging the object. Increase this value if you
find that you are dragging objects accidentally when you click
on them.
The only way to adjust the drag sensitivity that I know of is with TweakUI.
Download TweakUI here >>>
Microsoft PowerToys for Windows XP
http://www.microsoft.com/windowsxp/pro/downloads/powertoys.asp
These are all the Mouse settings that can be set with TweakUI.
TweakUI
[+] Mouse
Menu Speed
The Menu Speed slider control sets the speed at which
cascading menus automatically open when you move the
mouse over them. The fastest setting causes them to open
immediately and the slowest setting is extraordinary slow.
To test the mouse setting, right-click the test icon.
-----
Double-click sensitivity
Double-click sensitivity specifies how close together two
mouse clicks need to be (in pixels) to be considered a
double click.
To test the double-click sensitivity, click twice on the test icon
with the left mouse button. If the two clicks registered as a
double-click, then the icon will change.
-----
Drag sensitivity
Drag sensitivity specifies how far (in pixels) the mouse must
move with the button held down before the system decides
that you are dragging the object. Increase this value if you
find that you are dragging objects accidentally when you click
on them.
To test drag sensitivity, try to drag the test icon with the
left mouse button. The icon will begin dragging when you
have moved the mouse the necessary distance.
-----
Hover
This is used to detect when the mouse hovers over the icon to get selected.
The size of the region is determined by the hover sensitivity in pixels.
-----
Wheel
This is used to control the number of lines when the mouse wheel is
scrolled. This can be either one page at a time or a particular number of
lines at a time.
-----
X-Mouse
The “Activation follows mouse” checkbox enables X-Mouse style window
activation. When X-mouse style window activation is enabled, you need only
move the mouse into a window in order to give it focus. Normally you must
click on a window in order to give it focus.
=====
The following are the default Mouse options.
Open Mouse Properties...
Start | Run | Type: main.cpl | Click OK |
Buttons tab
Switch primary and secondary buttons
[[Clear the check box if you are right-handed and the left mouse button is
the one you use most often. Select the check box if you are left-handed and
use the right mouse button most often. The picture at the right indicates
the selected primary mouse button.]]
Double-click speed
[[Adjusts the amount of time that can pass between clicks when you
double-click your primary mouse button. If you are an inexperienced mouse
user, double-clicking may be easier if you drag the slider toward Slow. You
can test the double-click speed by double-clicking the image in Test
area. ]]
Turn on ClickLock
[[Locks a mouse or trackball button after a single-click, enabling you to
select or drag without continuously holding down the mouse button. Just
press and hold down any mouse or trackball button for a moment, and your
click is locked. With ClickLock you can drag objects, select blocks of text,
and open menus. Click again to release ClickLock. To adjust the amount of
time you need to hold down a mouse or trackball button before it locks,
click Settings. ]]
Settings button
[[Click to adjust how long you need to hold down a mouse or trackball button
before your click is locked. ]]
Pointers tab
Scheme
[[Lists predefined sets of mouse pointers you can use. Each pointer shape is
a visual cue that indicates what the operating system is doing or what you
can do in various situations. ]]
Enable pointer shadow
[[Specifies whether pointer shadows are activated. Pointer shadows provide a
three-dimensional effect on your pointer. ]]
Default button
[[Click to return your pointer settings to the ones Windows uses by
default.]]
Pointer Options tab
Select a pointer speed slider
[[Adjusts the distance that the pointer moves respective to the distance
that the mouse or trackball moves. For example, to move your pointer across
the width of your screen, you need to move your device further when the
slider bar is set to Slow than when it is set to Fast.]]
Enhance pointer precision
[[Specifies whether the enhanced pointer precision control is turned on or
off. Enhanced pointer precision gives you more control over the pointer,
particularly when moving small distances on the screen. It also provides for
quicker deceleration of the pointer when you slow down or stop your mouse.
Clear the check box to turn off enhanced pointer precision.]]
Automatically move pointer to the default button in a dialog box
[[Specifies whether the mouse pointer snaps to the default button (such as
OK or Apply) in dialog boxes. In some programs, Snap To may cause the
pointer to automatically move to the center of the dialog box rather than to
the default button.]]
Display pointer trails
[[Adds a trail to the mouse pointer, which makes it easier to see on Liquid
Crystal Display (LCD) screens. To change the length of the pointer trail,
drag the slider.
The slider is dimmed until the check box is selected. ]]
Hide pointer while typing
[[Hides the pointer when you type. The pointer reappears when you move the
mouse or trackball.]]
Show location of pointer when I press the CTRL key
[[Shows the location of the mouse pointer when you press the CTRL key. ]]
Wheel tab
Roll the wheel one notch to scroll
[[Defines how far a page scrolls when you roll the wheel one notch. You can
scroll a specific number of lines or an entire screen.
A screen is different depending on the size of your window and the program
you are using. It is equivalent to using the PAGE UP or PAGE DOWN keys on
your keyboard, or to clicking the scroll bar. ]]
Hardware tab
Devices:
[[Displays a list of devices, which includes the manufacturer’s name and the
type of device. ]]
Device Properties
[[Displays the physical location of the device you have selected. The
physical location can include things such as the bus number or the small
computer system interface (SCSI) identifier (ID). ]]
[[Displays the status of the device you have selected. If the device has a
problem, the type of problem and a suggested solution are displayed here.
You might also see a problem code and a number (for example, Code 10). If
you call a support line, this number can help you determine and diagnose the
problem.
You might also see a command button labeled Reinstall Driver, Restart
Computer, or Troubleshooter. Reinstall Driver starts the Hardware Update
Wizard, Restart Computer closes all open programs and restarts your
computer, and Troubleshooter starts the Hardware Troubleshooter. ]]
Troubleshoot.. button
[[Click to start the Hardware Troubleshooter. ]]
Properties button
[[Click to display or change information about the device. ]]
