I've been experimenting something similar then freezing,I would call it fanning.Every so often in the last three days,on very short putts(gimmes).As soon as I make the move to tap it in;fan!Goes right through the ball,no putt one more stroke added..Ive been using the beginners putter(discontinued) from the start and I know a lot of good well ranked players are still using it,and I hope it's not a way of getting rid of this old bugger.Please tell me it's my mouse that's not working right,but strangely it almost always happens when I'm having a very good round,making putts from 15-20 yards in succession then I have this half inch putt and I lose a stroke. I'm using a wireless laser mouse.Thank you for responding....Anybody?
