First it was just Chrome and the browsers, but now it's with every application. The scrolling ust stops working. Click and right-click work fine but scrolling is busted. Only solution is to reboot or to wait it out and it'll magically start working again. Often, it won't work for hours. This is a very big issue and I have no clue how to resolve it. Is Apple not picking up on this? We're supposed to be close to release and something as big as this isn't working. edit: On DP6.
