That fixed that, but SOMETHING is definitely, clearly messed up with the
latest updates.  I use Evolution and it lives in one of my workspaces on
my main display, and it's utterly broken right now.  The Evolution
window has somehow become as large as the entire display (it takes up
all the pixels on the screen).

So either I can't see the Evolution menu bar because it's hidden behind
the top Gnome panel, or else Evolution is hiding the Gnome panel and I
can't get access to it (that includes not being able to move my mouse to
the hot corner and get the HUD to show up).  It switches back and forth;
I can switch it by moving the Evo window to my other display (which has
no top panel) and back; then I can see the Gnome panel, but as soon as I
start an email message (in a new window) the Evolution window
automatically minimizes (which is weird) and when I restore it, it's
taking the entire display again.

I have a window list applet available but the right-click on the
Evolution window shows options for "Maximize", not "Unmaximize", so I
guess the system thinks it's not maximized.

I can't resize it; in no situation are there any window resize handles
available at any of the edges or corners of the Evolution window.  The
documented ALT-F8 key for doing keyboard resizing does nothing.  I also
cannot move it; I can't access the borders as they're not available and
ALT-F7 doesn't work either.

I've restarted Evo but no change.
