yes i understand the hardware device is, well, quite bad...

yes, still in the middle section. the righmost 1/2cm of the middle
section basically does not respond at all. I assume this is hardware,
however, I will go back to old 802 and double check and report back if
it behaves differently. . I have not noticed it explicitly before, but
when I think about it, finger drawing large circles was always funny.

yes, thanks. I am pretty sure I ran test way in the past, and it was
OK, but will try again.
