I appreciate the responses, but I'm more after corroboration that this IS in fact a Mastercam issue. I have not closed the door on other suspects, such as our network, which was switched over to active directory within the last 6 months. That said, I have no issues saving files outside of Mastercam...CAD models, spreadsheets, etc. Bobnob

Hello to everyone. I'm new to X6 in that I haven't touched Mastercam since v9, but have been using CAD for a while and have used many packages over the years. That said, I've never had so many problems doing the simplest things. Having worked for a software reseller, I am very hip to the fact that software companies aren't necessarily interested in fixing everything that's wrong with a particular version or release. But X6 is about as fun to deal with as wiping your rear with sandpaper. Even the simplest of operations, saving, never goes right every time, and i find this totally unacceptable. I'm currently using x6 mu3. The biggest issue for me is data loss during saving. Lets say I have file A open, and want to open file B. File A was just saved, but it prompts me to save again before opening file B. If I click yes, sometimes (not predictably) it saves file B as file A. So when I reopen file A, it really contains everything from file B. If I click no, it will do the same thing. Again, i cannot reproduce this on demand as software companies would typically require to investigate. If I have file A open, and want to create a new file, it does the same thing, but not predictably. I choose to save file A, when prompted, before creating a new empty file. File A will then sometimes be completely empty as if I saved the blank file over file A. Again I cannot predict when it will do this. Has anyone experienced anything similar to this? Without auto backups, I'd have been totally screwed and looked like an idiot to my boss. I'll own a problem if it's my fault, but this isn't one of 'em. Frustrated, Bobnob
