This is driving me crazy!

Problem 1.
I've created a presentation in Flash and published as a projector exe. When I open a PDF from the presentation the fullscreen projector reverts to windowed mode and that's it.

Problem 2.
I am also trying to launch an exe from the projector using:
on (release) {
	fscommand("exec", "folder/application.exe");
The file is in fscommand > folder > application.exe. It will not run when clicked. Am I writing the AS wrong?
