[APBeta] Removing catalogs

[Gary A. Ferguson]

 I'm trying to remove some catalogs from AP v2.0b29. I click the remove
checkboxes (24 catalogs), then click remove. The app hangs for about 5
minutes, then refreshes the window. The catalogs are still there! And the
remove checkboxes are unchecked. I then close the catalog manager, and the
app is now hung once again.

UPDATE -- just as I finished writing the above, the ap has returned  ---
hmm.. well, sort of. It repainted the main window, but I still can't select
or do anything.
