In the GEM application I'm writing, I'd like to be able to put a
bitmap/logo in the middle of the screen (i.e. like TURTLE or ARCGSH do).
I constructed one using the Resource Construction Program, and can
display it ok (as an object). But, when I invoke a desk acc. that
opens a window (i.e. Control Panel), and then close it, I get no
message from evnt_multi that the screen has to be redrawn, and the
accessory with the window does not update the stuff under it
(so that my logo disappears!).

I tried opening a 'dummy' window for the whole screen to get on the
window update list, but although now I get the update message, weird things
happen on the screen.

There just has to be a correct way of doing this (making sure that my
logo is always updated when necessary). If anybody knows about this,
I would be in your debt forever if you let me in on the secret.

Please send e-mail to andrew@cs.utk.edu.
Thanks,
