Yes, I have seen those other reports. It is hard to filter out the ones that seem applicable. Most are actually people having problems with their iPhone touch screen in general, not app specific. Others have the app freeze, or some touches not working while others in the same app do.
The ones that do seem applicable, don't have any solutions. If you found one that has, then I'd appreciate it.
I haven't filed a bug report, I assumed it was caused by something I did in the app.
