It turns out, deselect() doesn't get called by the
StandardMapMouseInterpreter. It should be, and I've changed it for the
release so that it will. We never noticed because we always tested it
with a drawing tool, and the drawing tool did the deselecting.
getItemsForOMGraphicMenu() should be getting called on a right-click.
It's coded for a cntrl-click to work as well, but for some reason my
version of Java isn't delivering the cntrl-click in the MouseListener's
mouseClicked() method. I haven't figured out why.

If you are using the released 4.6 version, you'll have to create a
different MapMouseInterpreter (extending StandardMapMouseInterpreter,
for instance), that actually forwards those calls to the GRP (the
layer). If you are using the version in the CVS tree, there's a
modification to the StandardMapMouseInterpreter where it checks the
layer via the receivesMapEvents() method, and you would return true
from that method in order to get the mouseOver() and leftClick()
methods called.
