when I hit escape, the game doesn't return me to the menu, everything just stops mooving (like I've paused it), the musc and the sounds keep playing, but I can't do nothing...to exit my game then I gotta press Ctr + Alt + Del and disable RF through the task manager

Also I got this problem with the screen fading, which somehow I feel has the same reason as the escape button malfunction:
when I exit a level, the screen is supposed to fade slowly, I made a script that detects if a trigger has been activated and then starts the low level fade command, every 0.05 seconds the script adds +3 to the fill screen area, but one day when I triggered the trigger, instead of fading, the screen turned immediately to black, then there was a delay - the order was still in action and when the fill screen area command reached 100%, the game returned me to the menu...the screen should be fading, but instead it turns black immediately and than after some delay, I get back to the menu...the fade thing was working...just one day it stopped working
