Right, if an error occurs in an errorhandler, VFP's error handler is used.

It probably woudl achieve what you want, but it seems like over kill to me. You can create a pretty solid error handler without going to another process.

What is bombing in your error handler? Do you have sample code? What does it do with the table?
