Is anyone else having problems with the touchpad? It seems like a software issue, but i'm not sure. - my left mouse button stops working or works intermittantly. Often if it seems to work properly, if you click and hold and try to drag a window, the window will end up being left behind at some point along the path because the mouse button unclicks on its own - right mouse button works always unless.... - whole touchpad stops working, or works with gaps in the input, or... - the mouse flutters around the screen like its on crack no problems with any usb mice or with the keyboard. and it seems like a restart can be the fix but most often isnt. i haven't heard anybody rant about their problems like this, which makes me wonder if something is wrong on my end. because for me, the touchpad not working is the most annoying issue, aside from how it hangs pretty hardcore now and then when you open firefox or another decently-sized program. anyone else having this? or do i have a defective unit?
