ActiveX Control property page problems.

I have made and ActiveX control in BCB and now I am trying to add
a property page to it.Here is my problem:
As long as I don't use the property page (as long as I don't open the
"properties" dialog in my container ) everything works fine.But if I
open the dialog even once, the control won't be "released" and I get
an interface leak!.I have used the code generated by the wizard without
any modifications ,but I still get the same behaviour.Any Ideas?
