some cleanup and trying to grok progressListener.  I get different states from the iframe when I define progressListener as a global variable, than when I try to build a new progressListener for each instance of the catalog.  I don't get the STATE_IS_DOCUMENT and STATE_STOP combination that Bill was looking for.  Bleh.  The problem is that in order to spawn, say, a copy browser, I need to know which window to put a tab in, and that spawn code is in the progressListener's state change function
