I believe it is a driver issue. I haven't seen the display problem in years. I'm also using a Matrox G450, but I've reinstalled windows several times over the years and I don't remember if the drivers were taken from the Matrox CDROM or some other source.

Yeah, I get the broken schematic wire thing on my workstation too.  Using a

If you like Protel 2.8 and don't see the benefit to 99SE, then by all means
stay with 2.8.  I still use 2.8 occasionally, for the pin swapping feature.
When manually optimizing routing for a 2 layer PCB.

The 99SE autorouter is better, but still not as good as it should be.  It is
useful for some digital boards.
