I just woke up and found my adress book, dial and drop buttons (green and red) are not functional.
As usual I removed the battery from the phone for more than a minute and inserted it again with no help. There are now more error messages popping up on the screen; uncaught exceptions waitforregistry(0x0222..)
This happened because I was charging the phone on my notebook and left it there the whole night charging.
So what's the damage? Does anybody know?
