I know I reported this a long time ago, but I can't find it, so I guess
that probably means you can't find it either...

In Gnome 1.4, the panel tasklist / window list / whatever you call it now
put windows in the same group (one box, with a popup menu) if they had the
same WM_CLASS property.  

This was correct and proper.

The Gnome 2 tasklist seems to only group windows that are a part of the
same *process*.  Or something.

The end result of this is that if I do:

    ssh -f host1 xemacs
    ssh -f host2 xemacs
    ssh -f host3 xemacs
    ssh -f host4 xemacs

I get *four* icons for xemacs instead of *one* and a popup menu.

This makes the tasklist damned near unusable, since I have so many separate
icons on it that I can't find any of them.  In Gnome 1.4, I would have
maybe six icons (with popups) on the tasklist, and it wasn't hard finding
things.  With Gnome 2, I regularly have 18 or more icons, no popups, and
it's a complete mess.
