Ah ok. Just that my button is really low on the left and squishy, where as the right side is fine.Thought that might've been your problem.
Do you have a MB?
I had the same problem, and it wasn't till the fourth top case Apple changed that it started working correctly. That paper solution helps, but it is just not the same.
Yep, I have a MB. I don't think I'd be able to send it in for repairs though, as I practically need it every day for work.
