Thanks Jim, I'll give your suggestions a try.

If it does still happen, I think you will find that it is looking at the same foxuser or config file, somewhere in the path.

If the error goes away in the test exe, put the wait window command as the first line of the main program of your app (after any parameter statement, of course), rebuild and run your app. If the error occurs before the wait window, you know it is something VFP is doing like looking down the path, etc., for config, foxuser files. If the error occurs after the added wait window command, then you know it is something in your code causing it.
