I have a unibody MacBook, about 7 months old. I seem to have trouble with the trackpad. First I was resizing a window in Firefox and it was like the curser got stuck down, I couldn't do anything because wherever I moved the mouse it would drag the window corner with it. I could use the command-tab to switch programs, but the curser was still stuck resizing that window. I had to hold the power button down to restart. After I rebooted it did the same thunk on the same Firefox window. I restarted again and now I can't click on anything, I try to click or tap to click and get nothing. I can move the cursed, but even over the dock it doesn't magnify it and I can't click anything. The strange think is I can two finger click and bring up the menu, but can't select anything. I don't have a mouse handy right now to see if I can do anything with that, and I don't really know keyboard shortcuts to use either. Any ideas on what to try? OK, after typing all that on my iPhone, I go back to my Macbook and it seems to be working now.
