I have an acer aspire running net book remix 11.10. the mouse pad freezes up completely and I must use an external mouse. if I reboot the computer the mouse pad will work again. i seem to have this problem happen in the middle of either using firefox or a few time while using thunderbird. anyone else having this problem. an external mouse works but scrolling is choppy or it scrolls part of the way down a page and then jumps to the top again. I don't recall having this problem after upgrading to 11.10 so I think it is related to an update. my Linux skills are limited.
