>1. With your project active - from the Project Menu - did you set main to main.prg?

Yes.

2. Can you do main.prg from the command window and run the program?

No. My main.prg calls for mainmenu.mpr. I get 'file does not exist'.

3. Can you do xxx.exe (your exe name) from the command window?

Yes, though the project mgr is still visible, everything works fine.

Where do I take it from here? It's gotta be something simple.
