Underscore or the plus symbol keys are not working on Windows 7.

Solved! Thanks!

I did what you said, but eventually used task manager to eliminate the process making trouble with those keys.

The problem was SoundBlaster Control Panel.

Solved it by removing the hot keys that were assigned to it.
