Caps reverse and other key issues

My Macbook has two strange keystroke problems.
1. While typing the caps lock will reverse itself. When I press caps lock the type is small case. If I unlock caps lock the type is Capitalized. If I restart the problem resolves but then resumes at radom intervals.

2. When I hit the fn, control, or option keys their white symbol appears at the bottom left of my screen and remains there until I hit the key in question again.

Any ideas how to fix these annoying issues.

Thanks
Richard

I finnaly figured it out. In System Prefs>Universal Access>Keyboard I had sticky fingers turned on. I turned them off and problem resolved. rijontry
