I'm new to CAD and, of course, to ViaCad. I'm running under Windows Vista Home Premium. My computer has an NVIDIA GeForce 6150SE nForce 430 graphics card.

I had a huge problem with garbage on the display, especially when the logicursor was active.

Here are some remedies I found that might save another newbie some headaches. None of this is mentioned in the manual, it probably applies only to computers similar to mine.

• If you have NVIDIA graphics, be sure to set your graphics card up to 'Let the application decide' for the image settings. This is done on the NVIDIA Control Panel, not in ViaCAD.
  
  
  
• On the Windows Control Panel
  Advanced Tools; Adjust the appearance and performance of Windows; Visual Effects tab;
  
  Set this to 'Adjust for best performance', or at least uncheck all the Vista graphics features that you are willing to live without.
  

This made ViaCAD run much better for me.

By the way, when I click on a .vc3 file, ViaCAD opens, but not the file. I just get Untitled 1. The default for .vc3 is set to ViaCAD but it doesn't work for me. Anybody got a fix?
