I'm using Ubuntu version 12.04, and after logging out and back in to restart Firefox bacause it wasn't responding, the screen turn into a bunch of text, so I had to turn the computer off and back on. Once i had logged back in (again), I got some "internal error" messages or something like that. When i was done with that i noticed that hover click, which was supposed to be on, wasn't working, so i went to system settings, universal access, and it said hover click was on. So i turned it to off and, and it logged me out of my account. Now whenever I turn hover click to on, the box doesn't come up, and hover click dosen't work; and when I turn hover click off after turning it on, it logs me out.
