Recently my mouse has been buggy (actually one of the reasons I'm switching from Windows 8.1) (I say mouse, but I mean mice, I've tried several). It will work just fine, but when I try to click in the unity launcher to switch to a program such as Terminal it won't work.

If I then use alt+tab to switch to Terminal I cannot click in the still-exposed Firefox to switch to that, AND it will change the mouse cursor to show things in Firefox as if I was still focused on the window (show the hand when hovering over a link). But if I then try to type in Firefox, thinking Terminal is now just shown over all windows, it types in Terminal.

In Windows 8.1 I had a similar problem, I would run a program, but would only be able to use my mouse in it to click and right-click and everything for about 20 seconds before it would stop responding. NOTE: my mouse still moves around, I just can't click and sometimes it won't even register as hovering over something.

I'm currently on Ubuntu 14.04 and the other OS is Windows 8.1.

Any help is appreciated, Ethan
