My company just installed SW 2006, we are currently using SP2.0 while I get 2.1 installed. We recently have found a repeatable CTD whenever we try to do a pattern of a linear feature. I have tried three different computers under two different configurations and the problem exists with all of them. This seems to be the only cause of the problem so far. I have used it on a system running an ASUS P4P800 MB, ATI FireGL X3 256 VC, 2 GB RAM, and Win XP Pro SP2. The other one is the same system, except 1 GB RAM and an nVidia GeForce FX 5200. I have installed all the certified drivers and the most recent drivers. The only thing that makes any difference is running it in software OpenGL. not a problem, except for the fact that I made sure to get a certified graphics card with enough performance to handle SW2006, and now I have to turn it off to run the program. My VAR doesn't have a solution except that it is a VC problem. Any one have the same problem or similar? Thanks!
