Nice to know. Thank you Simon.
Related question. Can you add a blank text file labeled safemode.txt to the Preference folder and the program will act as though you performed a Return To Factory Settings (RTFS)command without erasing preference files?
If so, perhaps a safemode command can be added to options. The command would act as a toggle where enabling the command automatically creates the safemode.txt file and disabling the command automatically deletes the safemode.txt file.
My problem is two fold. (1) I can never remember the name of the three preference files. (2) I forget about safemode until after I respond to a question. Return to Factory settings takes care of my issue # 1 and a safemode command would take care of issue # 2.

Then I wouldn't have to think anymore!!!!!
