I've recently moved to Ubuntu 11.10 (64bit, Unity) and encounter the following problem - at some point (it's hard to tell exactly, but it seems to happen after a couple switches between workspaces, but might as well be something else) hotkeys (like Ctrl + smth) stop working. I can clearly tell it happens in eclipse, but other apps might have the same problem. After some time they start working normally (after switching windows/workspaces may be).
It's not fatal, but really annoying. Is there some way to fix it?
I've looked at this question with similar problem, but answers doesn't seem to provide universal solution.
