I am having an issue with firefox and a matrox g450 graphics card. When I open firefox it opens in maximized mode and fits the screen just right but when i minimize or restore down and then again try to maximize, the window opens too high on the screen so the sizing buttons are not displayed and there is a portion of the desktop still shown at the bottom of the screen. In order to return the screen to normal maximized, I must choose full screen and then restore. This is maddening, and I have not seen it on any other firefox installation. Ideas anyone?

problem corrected by stopping the Matrox pdesk program.
