I think the vertical line behind the cursor appears for all cursors the do not have a shadow. I have confirmed the 'blue smudge' is actually the 16 bit of RED being turned off when it is on. As well as the font problem the other clearly visible issue is that many bitmaps have extra stuff turned on -- often affecting just the mask or existing background, not the intended image itself. > Note that this happened as a normal User, not an Administrator! ><snip> I haven't further tried to fix the problem. (I'm avoiding it bothering me while developing by remotely connecting using VNC, which avoids the original smudge and the mouse cursor issues.) > Anyone know if classes deep in the 1.1 .NET Framework can do this as a > User in Windows 2000? And can I fix it? Alternatively, anyone know another forum to try? Perhaps one related to video controllers? Regards, Mark Hurd, B.Sc.(Ma.)(Hons.) > P.S.
