Linux Client Screen Resolution

I have a few Linux Clients running FPMI. The same project runs full screen on a windows client with a resolution of 1024x768 but not on a Linux machine with a resolution of 1024x768. Part of the screen is hidden on the Linux machine. This is really annoying since the machine it runs on is a touch screen and the operator needs to use the scroll bars to get access to some of the buttons. Any ideas why there is this difference?

Probably a font issue. Take a look at this thread.
