No, this is through a combination of Windows 98 Plus Pack's built-in ZIP support and double-clicking on a ZIP file in Outlook. It saves the file in a temporary directory -- c:\temp\td_0001.dir\ -- and sets the file to +R because as soon as you close the program using the file it is deleted (so it makes no sense to save it). It's the setting of +R that's throwing out the library programs -- they start up in write mode, and choke if they can't get that. TheaterTouch Designer does not have this problem.
