Can't Alt tab in and out of GW anymore.

Before today. I could alt/tab in and out of GW with no problem. But since today every time I try it GW just stops responding and I have to close or terminte it via the windows task manager to get back in. The only thing thats changed today was an update to office. I can't see how that would effect GW in anyway. This happending to anyone else or does anyone have any ideas ?

PC specs

Core 2 duo 2.13Ghz
1.5Gb ram (800Mhz)
FX 7900Gt 256Mb
Win Xp sp 2 with all the latest updates.

I had an issue similar to this when i used to use a Logitech g15 keyboard... The drivers i had on were conflicting with something stopping me from minimising when running full screen programs..
I doubt you are running one of those, but even if you arnt, try updating your keyboard drivers because that worked for me.

I'm useing an el cheapo pc line USB2 keyboard but I had this before the problem started. I never seen any drivers for keyboards. But I suppose i can try and find some. Thanks for the info. This does not seem to be effecting anything apart from GW.

Well I changed the driver form the default one to a usb KB driver in windows and now everything is ok again Thanks for the info
