We just updated our 3 computers to 2009, SP3.0. That seems to work fine. However, the other users in the company that view our drawings with Edrawings are having problems. We just updated one computer to Edrawings 2009 to view our drawings and the screen goes wacko, as if there is a video card problem. This computer has the Nvidia Quadro FX 500. Shouldn't these cards work fine with EDrawings?
