Yesterday i was playing a game (GTA VC) and on a mission there you had to hold the SHIFT key pressed for a certain amount of time, after about 5 seconds i was sent back to the desktop (Windows XP) and the StickyKeys/FilterKeys popped up. Finding this annoying I disabled the 'Use Shortcut' feature for both of them. Sadly, when I alt+tab'd back to the game, it died and i couldn't alt+tab back nor use alt+f4/ctrl+alt+del so i had to reboot. Back in windows again i noticed that when ever i pressed caps/num or scroll-lock the pc speaker (on the mb) makes a beep. One beep when i enable them, and a different one when i disable them. I was totally clueless, I tried to enable the Sticky/FilterKeys again, but no go. I even uninstalled the game since i'm still clueless. Any ideas?
