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. > the right > and left sections will definitely not respond. if your finger is just > at the righthand edge of the middle section, then your touchpad may truly > be faulty. you can run a diagnostic: hold the "Check" gamepad key while > booting, and then hit ESC to get an "ok" prompt. then type "test /mouse". yes, thanks. I am pretty sure I ran test way in the past, and it was OK, but will try again. milan > > paul > =--------------------- > paul fox, [hidden email] > _______________________________________________ > Devel mailing list > [hidden email] > http://lists.laptop.org/listinfo/devel > > > ________________________________ > View message @ > http://n2.nabble.com/8-2-2-Beta-1-test-request-tp4112256p4127361.html > To unsubscribe from Re: 8.2.2 Beta-1 test request, click here. > -- View this message in context: http://n2.nabble.com/8-2-2-Beta-1-test-request-tp4112256p4127517.html Sent from the Software development mailing list archive at Nabble.com.
