Anyone have an idea why my mouse tends to creep towards the top-left corner of the screen during VS compilation? (Seems to be "going home" to coordinates 0,0...)

Isn't it an affect of video cards?  Has anyone else dealt with or witnessed this nuisance or am I the lucky sole winner?

Gratias!

EDIT: you know, it's not just during compile, it also can happen when running debug through the IDE. Is this a VS related oddity or not?
