Sorry, reported manually since I had to restart NB manually (totally unusable).

Thanks.

Not sure exactly what is going on, but I think DefaultEMLookup.propertyChange should call updateLookups asynch; in the features snapshot, uL is called just once but there are 293 listeners. (I have no idea how this could be true; LoadOpenProjects is a singleton, for example, and when I try it, its resultChanged is called just once per selection change as expected.)

Last report is from one year old build: 110728. Works for me.
