Is it possible to create a script at startup for the user to view the help-files on how to use the database, but select a checkbox 'Don't show help files on startup in future' so that they don't have to view the help-files each time they use it - only the first time.

Essentially, is it possible for the user to either 'Disable a script' by way of running another script or perhaps, setting FM to run a script only the first time that the user logs in, not each time after that?

Thanks so much in advance

You could set the startup script to check the user's preference and act accordingly.
