mouse leaves screen

[Jan Hackel]

I have a X setup to use two screens side by side: the first is my laptop's 
panel (1440x900) the second is a LCD (1280x1024). I run xorg-server 1.6.5 on a 
Gentoo Linux with KDE on top.

Everything is working perfectly except for one inconvenience. The mouse 
pointer will leave the screen on the bottom of the 1440x900 panel. I suppose 
it  happens because the height of the screen is less then the height of the 
LCD.

All window operations seem to work with the correct dimensions, e.g. 
maximizing a window will not make it larger than the panel actually is.

Is there a way to fix this?
