A curious little issue has arisen on my machine since my most recent reinstall of WinXP.
If I change screen resolution, the mouse pointer starts using the wrong cursor graphic on my second screen. So where it should be the standard arrow, I see vertical re-size. The busy cursor shows as the little hand etc etc.
There seems no logic as to which image is used in each case - it is different each time that the issue occurs.
The problem happens only after a resolution change - most often when I run a game full-screen and then return to the desktop.
