Mouse exits screen right

[GPG]

My mouse pointer cannot be taken off screen up, down or left. But it will
go off screen to the right, but only in the top 1/3 (or so). I have never
noticed this before, but my attention was drawn to it when I suddenly kept
losing the mouse pointer - where on earth is it?

I'm on XP Home SP2. Recent changes include IE 7 (beta) RC. And it may
have started when I got fed up with tabs and asked it to open things in new
window?.

Is this behaviour usual, just that I've not noticed it before?

My mouse goes off screen on the right and at the bottom, but not to the left
or top. It may have something to do with monitor settings.

That's normal behavior. The actual pointing position of the cursor is the
very tip of the arrow. If that tip is to be able to point to a pixel on the
extreme right or bottom edge, then by necessity the rest of the cursor will
go off screen.

If you have a Logitech mouse with driver installed, check in mouse
properties and change the pointer scheme to a left handed one - the arrow
cursor will point up and to the right. Now it disappears off the left side.

I have not made the behaviour sufficiently clear. In the lower part of the
right hand edge, the behaviour is as you state; namely the pointer remains
"just off screen and no more, as it were", and the slightest mouse movement
brings it back into view. In the upper part, however, the pointer can be
dragged "way off screen", so that a considerable effort of left mouse
movement may be required to bring it back - thus making one think that it
has ceased to exist (thinks "Oh dear, the program/system has crashed").
This is so disconcerting that I find it hard to believe that it was always
so.

In fact - the plot thickens. If a window abutts the edge of the lower
right screen, you can see that the pointer has gone nowhere by trying to
drag the edge of the window off screen. The left-right arrow indicator
remains in view and the window edge will not move. In the upper part,
however, the edge of the window CAN be dragged off screen, enlarging the
window. This also reveals that the pointer can be moved vertically while
off screen, but it cannot come back onto the screen below the level under
discussion. So there is a big space to the right, but only in the upper
part.

If I recall correctly the screen is addressed from the bottom up, making me
wonder if an arithmetic overflow of some sort is occurring, since the screen
size is 1280 * 1024.

Just an observation: this is the behaviour one would expect if a second
monitor were connected with an overlap to the upper part of the primary
screen. The mouse (and windows) can be dragged from one to the other only
where their borders are adjacent.

Do you have a multiple monitor setting enabled?

Ahhhhhhhh, good thinking. Yes, I WAS experimenting with trying to run 2
monitors a few days ago. Unsuccessfully, for reasons which I did not
understand. The video adaptor on the motherboard seemed to have been
disabled by the one in the slot. Not got round to understanding this, as 2
monitors is not particularly important to me.

Thanks for that.
