I just moved some of my functions to a new source file (Initialise.agc). Now, I can Run (Ctrl-F5) the game, but I can't Compile (F4, Ctrl-F4 or F5) the game, because it cannot find the Init() routine in the new file.
As you can see in the screenshot, the new file is part of the project, and Running works, so what have I done wrong?
