Although Mark may have correctly interpreted Randy Buckland's scenario,
I'm not convinced he has (but Mark's comments are none-the-less useful for
people to remember).  Randy said:

    I have a main window with a drawing in it. I have a child of this window
    that is unmapped that will overlay part of the drawing and has the
    attributes save-under set to true and backing-store set to always

Note that he said a *child* of the main window, not a sibling.

My recollection is that there was a "feature" in the R3 server that explicitly
avoided having save-under apply to the *parent* of the requesting window.  We
have since decided that this is not such a feature, and save-under does apply
to the parent in our current development server.

[Sorry, you'll have to wait for R4 for a fix from us.]
