>I have an app that I created that runs fine when I call it through the command window, but it hangs when I try to run it through a launcher exe. This launcher exe runs other apps fine; it's just this one that I'm having the problem with. It hangs when I do a set classlib or set procedure, or when I try to use newobject(). It's almost as if the paths are necessary for this to run, but I thought the procedures and classlibs were compiled into the app.

Add SYS(2450,1). If it helps, than you've a problem with VFP search path (SET DEFAULT and SET PATH).
