4/26/06 - I just got off the phone with an AccuRender user in Georgia. He says that AccuRender 4 is very unstable under NVIDIA's current released drivers. He said that at www.autodesk.com, he found a list of "approved cards" for AutoCAD 2007, that had specific details on versions that worked and versions that didn't. He said that the NVIDIA driver he downloaded from the Autodesk site fixed his AccuRender 4 crashing problems. Here's the URL:
