In the Force Quit Applications list, look for Finder.The good news is that restarting Finder is fast and easy: If it goes belly up, you’ll lose the ability to drag files from one place to another. The Finder application is the beating heart of your Mac’s file management system. Assuming that you’ve eliminated the mouse hardware itself as the culprit. If it happens everywhere, well a system level issue seems likely.
