Thanks for the suggestion. Unfortunately it does not fix it.

I rebuilt it in VFP7 and it gives the same C5 error as happens with VFP9.

I know about Doug H's suggestion about WITH ... ENDWITH being the cause of some C5 errors. However, in this case, because the two options run fine independent of each other, and the error only arises when the form that has the RMchart activeX follows the form with Crystal reports, it must be some kind of interference form the RMchart activeX control.

Any other ideas on what I can try to resolve this?
