Using resource editing utilities such as ResEdit, some Macintosh enthusiasts modify their system and applications to suit their personal preferences. An example is modifying command key equivalents for menu items.
Claris Technical Support does not support the use of ResEdit or any other resource editing utility. Resource editing has several implications for Claris applications:
Compressed Resources Un-modifiable:
The resources of some Claris applications are compressed. The benefit is that application size is decreased, taking less space on your hard drive. However, a side effect is that compressed resources cannot be edited.
Updaters:
Claris releases updaters from time to time which take an existing copy of a Claris application and create a new version which is up to date. Updaters will only work on unmodified Claris applications. If you run an updater on a modified Claris application, you will get an error and the update will be aborted. The solution is to reinstall the application from your original diskettes and run the updater on that copy.
System Crashes & Anomalies:
ResEdit is a powerful program in that it can change the actual programming code an application uses to run. Used improperly, it is possible to undermine stability or even render an application useless.
