I have a WPF DLL containing a few forms I'm trying to call from a VB6 app. I've got most of the interop figured out. I can open the forms fine and for the most part they work fine. They operate on their own and don't need to communicate with the VB6 app. The problem I'm running into is that when the WPF forms open the first time I hi...
