I have a new 19" monitor connected to a Rage 128 video card in a beige G3 running OS 9. When I first got the new monitor, I attached the old one to the built-in monitor port and played around with dual monitors for a while. I got rid of the old monitor but can't figure out how to get the computer to forget about it. The monitor Control Panel continues to show both monitors. Even a clean install of OS 9 doesn't work. I would ignore the problem but every so often my cursor disappears into the nonexistent monitor screen and it takes a while to find it. Any suggestions would be greatly appreciated.
