Does any one have any experience backing up the vue directory prior to upgrading? I guess there could be registry updates that won't get caught, but that too could be worked around. I kinda want to upgrade, but with all of the other problems, I'm a little nervous. It works fine right now, except for a few weird material problems (try editing a material, and then canceling the edit box....it can sometimes really get things messed up) I'm using 4.03-02. I'll probably give it a shot this weekend, unless anyone can give me a reason to stick with 4.03 eric
