Larry:

Agggh! Thanks for confirming the position. Nothing wrong with VFP or my framework, just the workman at the keyboard <s>. I was setting focus to the container which housed the standard OK/Cancel command button pair ...

THISFORM.Cntokcancelcustom1.SETFOCUS()

as opposed to ...

THISFORM.Cntokcancelcustom1.cmdok.SETFOCUS()

Which works fine called from a processing method called by the option group's click event. The nice thing about getting this sort of quick clarification when your feeling "brain-dead" is that I don't have to pester the framework vendor over something that is basically a typo and then really look like a dum-ass!

I really appreciate your fast and responsive help.
