Yes, which is why I, too, was surprised.

I just installed 1.7.13, and the behavior is still there.
It goes away when something completes, which happens when
all the windows started by .startxwinrc are gone.  If I kill
it, then all those initial windows die.  Perhaps this is all
normal, *except* that the run window is displayed.

Yes!  Now the xemacs icon is back to the way it used to be.

Maybe; if I find one I like :-) ...

Actually, -iconic does not work; neither does it work to set the iconic
resource to true.  Seems to be an xemacs thing.  In fact, here is a quote
from the FAQ:

"Ugh, this stuff is such an incredible mess that I've about given up getting it to work. The 
principal problem is numerous window-manager bugs... "

However, I find that the .XWinrc MINIMIZE style *does* work ... but of course
only for windows I create later.  And the class name is "emacs", not "xemacs",
hence a STYLE entry of: emacs MINIMIZE ...

Does this suggest to you any other way that might work to get an iconified
xemacs from the .startxwinrc file?

That is indeed now fixed.

Thanks for all the fixes!     E
