I have seen similar behavior. However, not having been to 2005, I cannot compare. Do you have a list of specific files that exhibit this issue? I do know that, for instance, the Smartutilities break DXDesigner, and should only be added into the WDIR when you run Expedition. I suspect that DX either cannot handle more than 3 paths in WDIR, or it does not handle the sections in the scripts.ini file properly. On another tack, This suite sets WAY too many environmental variables (44), that mostly seem to do nothing. And don't forget to add the 25 additional variables to support analog simulation on top of the 44. They should either be built in to the tool, or placed in a common configuration file. This is, dare I say it, eXtreme?
