I hope somebody has had this problem before and can help me resolve it.When I load any aircraft, including the default C172, the 2D panel is not visible with the screen in Full Screen mode. All I get is a wide black band across the lower part of the screen. If I press W for the smaller gauges across the bottom, the scenery view expands to occupy the full screen but no gauges appear. I have Global On and Main Panel selected in theViews/Instrument Panel menu. Also the mouse pointer is black rather than the usual white.When I press the ALT key to get the menus across the top, the 2D panel appears as normal, and the mouse pointer turns white. If I press the ALT key again, or click on any of the icons on the panel, the panel disappears and the mouse pointer turns black.If I exit Full Screen mode and just go back to a maximized screen, the panel appears and everything functions as normal.The virtual cockpit panel does not appear to be affected by this and apperas to function normally in Full Screen mode.This only appears to have occurred recently. I thought it might have been caused when I installed the CalClassics DC6B but I've removed all the files for that and it's still the same.I've been using FS2004 for some years and it's the first time this has occurred.Look forward to receiving some adviceGraham
