I seem to be having a bit of a problem with one of the buttons (exch) on one of my machines. I first noticed this when carrying out a test but as you can imagine, this is obviously a significant problem with the all round gameplay, nudging itself / holding etc.
How much of a problem would it be to disconnect the button in question to give it a bit of a once over and replace it. Probably easy enough I suppose, just never done this before.
Cheers, Stu
