Keyboard Cut & Paste Not Working After SP2 - BUG!!!!

[Guest]

I've already posted this problem before, so please bear with me. After
installing SP2 on XP Pro I can no longer use Notepad & Wordpad with the same
efficiency. When using the Copy operation, in Notepad it only works for the
first couple of attempts (1-3), in Wordpad is appears to work always. By
'work' I mean it transfers the selection to the clipboard. When it doesn't
work in Notepad, nothing is reported and nothing changes (literally).
When using the Cut operation, in Notepad it usually works always, in Wordpad
it appears to work always. The only problem is that, in Notepad, it only
pastes 1 or 2 times before clearing the clipboard.
When using the Paste operation, provided information was copied to the
clipboard successfully, in Notepad it seems to work but will sometimes clear
the clipboard after a paste, in Wordpad it appears to work, except when you
have also selected the 'end-of-line' space (the one that represents ENTER),
in which case, instead of pasting the text, it pastes a screenshot bitmap of
the current full screen. WIERD!!!!
Also when using the keyboard movement commands (particularly the
Ctrl-Home,Ctrl-End combinations) Notepad will mosttimes clear the clipboard.
This problem is not restricted to my system. I have experienced this problem
on three different systems already, and I have several reports of this same
problem occuring for some of my users. It also only happens after SP2
installation.

I have no idea where to leave bug reports, so that's why this message is
pasted here.

In previous versions of Windows there used to be a "clipboard viewer",
a cute little gadget that let you peek into the contents of the clipboard.

Somehow in XP that had parts of its anatomy removed and you need to know
how to find it if you are going to use it.

This is just a guess but maybe you can peek at the clipboard with this and
get some clues that might help.

Run
C:\Windows\System32\Clipbrd

(it might not even be installed in some cases)
but if you have it then maybe it can confirm the behavior you are seeing.
Maybe that can help goad someone into a little action.

I just sincerely tried to reproduce your problem but I can't seem to make
it work. I opened up Notepad and Wordpad and copied things back and forth
and back and forth and couldn't get it to fail.

I didn't try the keyboard problem but the cut and paste seemed to work.

I hope something in thi might give you a clue, if there is anything else
I can try to help track this down then poke me.

thanks

After checking out the clipboard viewer I found an interesting thing, it
appears that our KVM switches are not compatible with Windows (or vice versa,
or just the KVM's not truly PS/2 standard compatible [despite manual]). The
problem is has the following interesting properties:
a) It appears to only be the extended keyboard movement keys
(arrows,home,end,pgup,pgdn,ins&del), the ones that are NOT part of the keypad.
b) When using LSHIFT (& LSHIFT only) + any extended movement key, the
problem will occur on the KEY_UP of the movement key.
c) If the LSHIFT key is NOT released after the movement key has been
released, then the problem will occur rapidly. Without a stopwatch (or system
debugger), I'd hazzard a guess and say that it is occuring at the current
keyboard repeat rate.
d) The 'problem' is as follows: a full screen snapshot (PrintScreen style)
is copied to the clipboard in addition to the normal keyboard responses.

It only seems to happen on the computers attached to KVM stations (we only
have a couple) and does not appear to be any 'keylogger' or such. (I can't
find any rogue processes) Every other computer I've tried that was not
attached to these boxes (I haven't tried other KVM boxes, can't get my hands
on any) does not encounter this 'problem'.
At first I thought it was the KVM box mistaking scancodes or only passing on
part codes to the computer, but it takes the screenshot IN ADDITION to the
normal key actions (arrows move, insert inserts & delete deletes, etc).
A decent workaround is to turn the numlock off and use the keypad for
navigation, but I must admit, I'm curious now as to what could be causing
this problem. I'm not sure where to start looking, so if anyone has any
test's they would like me to run, or any ideas then just reply, & I'll see
what I can do.

Without the clipboard viewer I'd guess you'd never been able to track
the problem down, cute little gadget that.

Interesting but maybe useless exercise, what if you slowed the keyboard
repeat rate WAY down? That might confirm or refute the guess that it
is the repeat rate. But I don't know that would help diagnose this.

Ah, maybe it being KVM related was why I couldn't reproduce your problem.
If it is KVM then the make/model might make a difference. I've got an
Airlink 2 port MiniKVM somewhere and an ancient Belkin buried. If I can
find those I'll see if I can reproduce your problem. You could also
rattle the door at the KVM mfgr and see if they know anything about this.

Glad I was able to point you at the viewer so you could see the clues.
