>Try enabling: SYS(2335, 1) - that will force VFP to error (and hopefully be trapped/logged by your error handler) instead of display any UI, just in case that's what's happening.

Using sys(2335,0) which should be the proper syntax for your suggestion does not help things. From reading several sources on 2335, it seems this is more for a remote automation server. I am not building one of those and don't need to unless I misunderstand something about building a service.

If I do can you point me to some better documentation than I have.
