Since the other frames are not really visible, treating them as
iconified makes some sense.  But then I don't understand your original
report: you said these frames are not updated, but since they are
obscured, what does "updated" mean for them?

IOW, I'm now confused regarding the original report of the problem you
have.  I guess we need to start from the beginning now, so I'm asking
you to describe in more detail what doesn't work in this situation.
