>I know I should read the manual, but is it possible to have multiple copies of config.fpw in separate directories for each app/project ? So the effect of turning the screen off wouldn't affect all forms that I might want to run ?

If an exe finds that file in the same directory its run from, thats what it uses. You can also use the command line to tell which one it needs, or you could build the config.fpw right into the exe and not worrty about anything else.
