Hi guys, I have a 15 inch mbp and I have been having some problems with expose recently. When I do two finger swipe up/down for scrolling on webpages, it also does Expose as if I am using 4 fingers. The regular 4 finger swiping still works, but now if I scroll too fast with 2 fingers, it does Expose as well. Does anyone know what the problem is? I have tried googling but I haven't found anything related to this. Thank you.
