I have but doesn't make a difference within the project! Only from the command window. I think on compiling into an exe the .fxp files are regenerated anyway.

Seems a bit strange as all the files are in the project and so when compiled it should be able to find the programs also stored within the project, rather than having to reference the path to the program.

This is getting me thinking that my project is having problems, but it is really very puzzling!
