Tor, this looks like some GSF navigator threading issue if t_h is right that this is not explorer problem. Can you
please look at that?

This (and some other related functionality problems) should be fixed now, as of changeset 03071a0eb8ed.  (And some other
navigator related problems in 1d8b57cce2e0, 50bded4ca7b5, 153928aad54a).

This navigator bug has been there since the beginning (NetBeans 6.0).  The reason it suddenly spiked in number of
exception submissions recently was related to the various node performance changes elsewhere. But that was just the
exception stacktrace. I uncovered several functionality related problems where for example switching files a lot would
eventually cause the navigator to stop updating the navigator selection based on the caret.
