How to refresh a ActiveX control's property

[Coco]

I made a ActiveX control and it's property sheet.If I directly changed the property in property window all was ok.But when I changed the property in property sheet which I made it I found something was strange.Although I saved the property in sheet the property in property window hadn't been changed.And I move the control or debug it the property can be saved.

Could you help me?

Thank you.
