I am getting an issue when trying to save an assembly.  I can read the assembly and then immediately save without problem.  I can add components and save without problem.  If I add another mate condition (there are currently 3 mate conditions) I cannot save - I get an access denied error.  If I continue to try to save, I get a 'docfile corrupted' error message.  Once I get the access denied message, the file has to be closed without saving and re-opened to enable any saving.  I am in a multi-user environment saving to a 'my documents' area of a shared network resource.  Any ideas?
