Hey,
So I've used Action for quite some time and never had problems. Until today where I had to record some WoW footage which went totally tits up - To be honest. Right off the bat it crashed the entire game, screen kept blinking like the driver tried to recover but never managed to which resulted in me having to hard reset my machine.
Then I finally got it working but the problems continued. In Fullscreen ( Windowed ), which I usually play in and set it to record the monitor itself, my game will "lose control" every 5-10 second. I just stop and need to press the keys down again to move which is highly annoying.
When entering real full screen mode, the second I try to make the window active by clicking anything with the mouse, it minimizes the window - ALL THE TIME!
When I turn off Action, everything works perfectly again.
