Computer Forums - Systray Icons

:mad:Hi I don't know if I have the correct title. The problem being when I hover over on an icon in my Systray. The 'little box' which opens telling you what the icon is. Is hidden behind the Systray. I can just make out the top of the box. I have the setting which hides the bottom tool bar when not in use.
This happend a few years ago and someone told me how to rectify the problem but it's that long since I've for gotten Anyone know what the problem is?
