Gamecube controller problem. Not sure how to fix.

[kostyv]

When I use my gamecube controller with the mayflash adapter, the main analog stick does not work properly. For example, when I come across an option menu in a game, and i click down once on the main stick, instead of it moving down just one selection, it will move down many selections.

Replay                                                    
Options                                                    
Exit    

If my cursor is on Replay, and I hit down once it will skip to exit or continue, and I have no control of this and it is a huge inconvenience.

Does anybody know how to fix this problem?
