I feel extremely stupid. I somehow had the "F-Lock" key on.
I just depressed it and now I can do Control-F9. Thank you
so much for all your help. I can't seem to do the unlock all
worlds but now that I can do the Control-F9, it doesn't matter.

Maureen, Thanks for your answer but unfortunately, this also doesn't work. There is no open all levels category. The only categories are: Music VOlume, Resolution, detail Level, Full Screen, English, No Time Limit, Visit us Online and Main Menu. I do appreciate your trying to help me. I'm beginning ...

I've been told that if you cannot do a level that you go into that level and hit Control-F9 and it will let you finish it with 1 point and then you can move on to the next world. I have tried doing this and am not successful. I am in World 3 and cannot do Level 10 and would love to go on to World 4....
