I have a Cyborg R.A.T 9 mouse and when ever I plug it into my computer, I can't left click. Strangely enough, the mouse works fine at the login screen, but not after I log in. I'm also not able to alt+tab to other programs.
I've looked through the other questions for the R.A.T. 3, 5, and 7 mouses, but none of them have solutions that work.
I'm running Ubuntu 12.04.1 on a Lenovo ThinkPad T520.
