I'm developing a container part that initially embeds some other parts in itself. Question: how soon in the creation of my container part can I embed a new part? Right now I'm doing it in the first call to NewFrame after I've done the FW_NEW to get the new frame. Then I acquire a new part and call SingleEmbeddedmumble to embed the new part. I blow up later with an unmapped memory exception. Am I attempting to do this embedding too soon?
