I suspect about CM9
I'm with the same problem, and I suspect about CM9, using AROMA the problem seems to be vanished... but, after boot (in the Android) the touch problem get back.
It seems I'm having a similar issue as well, and it all began after installing Jokersax's CM9. My touch screen doesn't work at all. I think I'm just gonna take it in for repairs.
We should send a bug report with our accumulated info though to Jokersax, no?
