Hi, Have a Dell Optiplex SX260 with 1504FP flat screen, Intel Extreme Graphics 82845G, analog cable. If I run some old DOS software that launches in text mode, switches to graphics mode and eventually switches back to text mode - it all runs no problem. The DOS session while in graphics mode runs fullscreen and in text mode afterwards after quitting is in fullscreen mode. But at this point if I press Alt-Enter to windowise the DOS text box and restore the Windows graphics screen, the monitor goes black and a monitor message saying "1. Analog Input". There is nothing for it but to reboot. I have tried turneing off monitor and on 20 second laters, fidd. How can I change this? I want to run the old software and somehow restore the graphics session of Windows afterwards. I checked Dells web site - found nothing on this, FAQs, support etc There is a USENET newsgroup on Dell - will try this later. I have something else I will retry and that is to enable the Monitor hotkeys and try Ctrl-Alt-F1 which does "enable monitor" Anything else I should do? Perhaps change something under _DEFAULT.PIF properties ? Thanks Stephen Howe
