I decided to remove some show screens (that I don't use) from appearing in the menu list by putting a tilde in front of the filename in the templates folder within the Preferences folder.
This worked fine....then however I tried to restore some templates that were already "tilded" out by removing the tilde. For some reason this does not seem to work.
I tried doing this both with KJams running and also with KJams closed. When I restart KJams and "reveal preferences" I find that the templates files are back to what they were before the changes. That is, the Prefs don't seem to "save"?
I'm obviously having a "dumb" day today

Cheers
