where do applications go? (iconify app not show anymore)

[nasser abbasi <nabbasi pacbell net>]

Ok folks, I gave up :)

this is gnome 1.0 RPM on RH 5.2, with E 0.15.5.

for some reason, when I minimize a windows (such as netscape browser),
or an xterm, the window disappear from desktop, never to be found. so
I can't open it again.

I looked everywhere for it, under all the other windows, it 
is gone. I have only one desktop. 

it is not on the gnome panel. but the app is still running.
(I see it with ps command). 

any idea? how do I get the running programs to display on gnome panel
so I can easily switch between windows? There does not seem an 
obvious way to do this. (they used to do that before, but now
for some reason, gnome panel is almost empty execept for the
standard icons (netscape, help, GNOME configuration tool, GNOME
control center thing).

I am sure I am overlooking something too simple and obvious here!

thanks,
Nasser
