I've just installed some new graphics drivers for my tx2 pro [sis 6326] as i couldnt get more than 16 colours on the old ones and that worked but now I have mouse trouble. The cursor just won't move from the top left hand corner. For some reason it starts working again whenever I visit http://www.sis.com.tw/support, as soon as the window opens. It freezes again when all open internet explorer windows are closed [I dont have to stay on the sis site.] This is seriously freaking me out. Any idea as to whats happening?
