About 10 minutes ago I was transferring some files from a USB stick when my Macbook just stopped responding to the click-pad. I can't right/double-click on anything! The cursor works fine and I can move it around but if I hit the clickpad, nothing happens... I can't get into anything, change anything... I don't know what to do. I tried using the trackpad to click instead but all that does is give me a lasso tool and still can't click anything but it selects icons on my desktop. It also just selects the top bar automatically but I can't click on anything in the menu. I thought it was my hardware but I plugged in a mouse and still nothing! I can left-click with the mouse but not right-click. I've tried rebooting and nothing changed. It's like my right-click is constantly pressed down. But it's not physically. Also, when I leave it alone it tries to go into the screensaver but constantly comes back out again, so it results in flashing between Flurry and my desktop. Also, my keyboard is working fine. Please help? I have NO idea how to fix anything if my right-click isn't working!!
