Could you help me with hell of a weird issue?
I use Intellij IDEA 13 on Ubuntu 14.04, and from time to time my keyboard completely (yep, completely, it's not about shortcuts) locks in IDEA. I still can do anything I want in IDEA with my mouse, also I can use the keyboard everywhere else except IDEA. And it can be fixed only by restarting IDEA so far.
Can anybody give a hint, please?
