By chance I managed to enter the magic combination of pressing the Shift key 5 times...... The Windows "Sticky keys" turned on ! I tried all possible combinations to turn that sticky key combination off.... but nothing seemed to work.. Even trying to disable the sticky keys didnt seem to work! I never really felt so helpless before! At last I had to restart my machine to get rid of this stupid feature! Now I am of the general opinion that the sticky key feature is a REAL neusance to the already "not so rosy" world of windows! WTH!
