Ever since I installed USB Overdrive on my imac last night, my mouse has been clicking randomly whenever I move it. This is making it a REAL pain to do ANYTHING, especially considering that I'm a graphic designer and need a STABLE mouse. This thing just clicks, the scroll button clicks, and the right button clicks... whenever I'm moving it. It's incredibly frustrating and I don't know how to change it. I'm scared to move the mouse over ANY files because it will just drag things randomly or open things that I didn't want it to open. Seriously annoying! I've uninstalled USB Overdrive - that didn't help. Switching to another USB drive didn't help. And I'm worried that buying a new mouse won't fix it. What do I do? I don't want to have to back up my entire computer and reset it just to fix the damn problem. I have a 24 inch imac with Intel and the standard wired mouse that comes with it.
