>>>In the last maybe 6 months something strange started to happen - on CTRL-c or CTRL-V the mouse pointer disapears and for a few seconds the computer seem to freeze. This is not limited to VFP, it happens in all Windows apps (Word, VFP, Outlook, ...), and it happens on my co-workers computers too. It is not happening all the time, in fact most of the time it's 'normal', but it does happen often enough to make me ask. Does anybody know what may cause it?
