As the title says, sometimes I (left) click and it registers as a right click. When it does it, however, I can right click (with the right mouse button obviously) and it seems to fix it. Only started happening recently. Not a big deal it just gets annoying.
Also it only happens after unlocking my computer. Even then it's only a small percentage of the time. And the buttons sticking together is out of the question, as they don't touch.
