SpaceSaver, a file compression utility which is part of the Stuffit Deluxe 3.0 package by Aladdin Systems, seems to conflict with the Claris Help System.
For example, with SpaceSaver installed, clicking on the Script Reference button in Resolve Help, will result in a message that there is not enough memory. Also, trying to access help during a scripting session will bring up a message that the Help System cannot be found.
SpaceSaver is a system extension and can be disabled temporarily by holding down the Shift key while starting up your Macintosh (with System 7.X). To disable it completely, or if you are running System 6, remove the file from the system folder.
Aladdin Systems states in their release notes that Claris plans to fix this incompatibility. No release date has been announced by Claris as of 3/24/93.
