Never seen so many problems with a release as this one (Using since 1999). Open a file in SWx - crash. Open a file in win explorer. - crash. Won't regenerate models and assemblies until close and reopen. Space ball crashing and loosing settings. App hang and crash nightmare. SP 0.0 did not clean out the registry either. ( And yes, a dell T7500 with the right stuff and drivers.) Happy to report SP1.1 fixed all that, using less memory and "seems" to be loading/responding faster. Maybe there was some reason we didn't load the next version until SP 3 or 4. Thought someone might like to know.
