Don't know, but I never use FrmSetActiveForm anyway. I use almost
the same code as you, just without the FrmSetActiveForm line. And
It works like a charm. Why do you want to make the form active in
the first place? I think this is done implicit by FrmDoDialog (or
FrmInitForm?).

I don't really know, but I would interprete the "save bits" as
following: If this flag is set, I want that the OS cares about
refreshing the screen, when the form is dismissed (by either
restoring the saved bits or by queueing a frmUpdateEvent event.
Otherwise I will care about it myself. So yes, I consider the
current behaviour correct.
