Re: Menu bar visible in fullscreen wine programs
Try the following.
Install the Compiz-Config Settings Manager.
Run it by typing CCSM in the Dash.
sudo apt-get install compizconfig-settings-manager
In the section entitled "Workarounds" (in the "Utility" section) make sure that "Legacy Fullscreen Support" is checked. I can't guarantee it will work, but it can't hurt.
If you are asking about a problem with your system, make sure to give details about your setup. OTHERWISE, NO ONE CAN HELP YOU.
