Comment 6 for bug 1033197

Ok i assumed it was unity because i could not replicate the issue. I have replicated it.
To fix the issue open fbreader and press the o key alone. This will open the config menu then go to the keys tab. In the action for keys area press any key i used q. Then select toggle full screen mode. Then hit apply and the q key will toggle full screen.
Please let me know if this works for you.
