Guild Wars Freezing

It seems my Guild Wars client is freezing evertime i shift+ctrl while in-game. The first time it happened it was easily reproducable, so i reinstalled GW. Now after a while it seems to reappear.

This seems to be a bug in guild wars, as i was able to play GW for over 2 years perfectly, then it suddenly appeared, so i dont think this will be a computer specific problem.

This is most definitely not a bug within GW. It has to be something on your computer.

Sounds more like another conflict with MSN+ or some other program that is intercepting the shift+ctrl.
Did you install anything new or upgrade something around the time this started?
