Open and run the attached VI first in LV2010SP1, then try in LV 2011f2.

So it sounds like it's a dead ERF...
Event structures which use this event registration refnum no longer receive any dynamic events.

The UI lock is indeed weird.
After you unregister an event registration refnum, I'm not sure if you're supposed to be able to reuse it. I'm under the impression the way one usually handles dynamically registering/unregistering events is by using null refnums for unregistration:

I just ran into this issue with some code I wrote in LV10 and then tried to run in LV11. This thread proved most useful as MJE's solution worked exactly as advertised, so a big thanks and kudos! But I have to ask, the idea of NOT using a function called unregister for events and instead using null refs to ... you guessed it ... unregister for events seems like some pretty arcane knowledge. Where did you get this tidbit of information?
