Hi Dave, See my other post. The essential point here is that "Edit" means exactly that - there's got to be something loaded before you can edit it. I must admit that I couldn't quite decide how/where to put the application configuration stuff, so it's split between the File and Edit menus. I suppose I could create an AppConfig menu with Add. and Properties. entries below it, though I could also argue that I should add App Config as an option to the Surfaces menu, showing it as a sub-menu with Add. and Properties. options below it. Which makes most sense from a users perspective? Best wishes.

I select my control surface, and select edit/application configuration from the menu. The program crashes on an unhandled exception. The exception is caught however, so this may be some code that has been left in by accident. Perhaps I have done something wrong, Best, David.
