Well, I gotta eat CROW, CL did respond to my email this evening .. so now I know the answers to my questions. After I posted my first reply, I thought a little more about your problem. I did have the same trouble with a Dell laptop at work. I do not recall what the graphic was but at any rate, the problem occured because I was using a combination of refresh rates, color depths, and screen size that just was not going to work. Hope this helps.
