I accidentally deleted all the clipboard maps and the buttons that allow you to Add, Edit or Delete disappeared so there was no way to add any maps back and the only way to fix it was to quit and delete the ‘lst’ file to activate the default 'lst' and start over.
The second problem is that sometimes the map displayed will not respond to the 'apply delete' click. For instance, if you've deleted a couple of maps and click Add or Edit or maybe it's the map list box, and then click delete and apply, some times the current map remains and it's still in the map list. I wish I could be more helpful with this one.
Then there's the radio buttons for Add, Edit and Delete instead of push buttons.
