The objects aren't that complex, bascially it just opens some tables, adjusts them or returns calculations based on their content, then cleans up after itself.

I'm going to try Glen's idea of using NEWOBJECT instead as I can bypass the loss of the CLASSLIB setting by specifying the class as a parameter, I'll let you know how it goes one way or the other.

Thanks to everyone for your feedback.
