Why can't I select "Propane"?

Q: Why can't I select the Propane category for a charge?

A: Some older versions of the program added an extra space in the default text for the Propane category when a new database was created.  To fix this, go to Maintenance / Pick Lists / Transaction Categories.  Check the "Allow editing of fields" box at the top, and then click twice on the word "Propane" under Normal Text.  Move the cursor to the end of the word and you should see it go one space past the end -- use the Backspace key to erase the extra space, and press Enter.  Click Done to save the change, and it should work now.
