Alt+Tab

[viion]

I didnt care much for this but as I now use a laptop a lot of the time I'd really like to see this fixed.

Not only just for the performance increase but when stuff like Windows Update pops up like "YOU U WANNA RESTART BRAH" it minimizes the game ><

Not to mention that anti-virus software may pop up a scheduled scan/database update window, or some other application you're using may choose to let you know it downloaded some minor update - and crash the game in the process. Plus the accidental WIN-key/multimedia keyboard presses. Oh and if you've got some instant messenger like MSN, ICQ and such running in background it's a pain as well.

Simply put, alt-tab crashing needs to go.
