I am developing a resource DLL-based dialog that inherits from the Dialog class.

How can I prevent the automatic storage of the dialog size and screen position in Origin?

As I am developing, I'm changing the size of the dialog in VC++ but the size of the dialog remains at the "old" size from last time I ran it in Origin.
