Part of Touchscreen Not Working Intermittently

[chuck07]

Next in the chronicles of broken Thunderbolts comes a touchscreen that intermittently does not work.

While typing a text message, I could not hit where the 'n' is, and I had to hit on the outside of the 'b' and 'm' area. I thought it was a fluke, but I could hit anywhere else and it worked perfectly. So I pulled open 'Chalk Ball' and tried to use the screen in the same area, but input was not taken there.

A minute later it works again.

It has since gone out two or three times, for a minute or so. Not always while sending a message nor using the keyboard.

I am trying to figure out how to reproduce it so I can go to the store and get a 4th replacement.

Has anybody else had the problem?

Recently my Thunderbolt stopped working on the left mid portion of the screen.  It is intermittent...and is normally resolved by restarting my phone.
