I upgraded a year ago to the version available then (the one prior to 4.81).
The system hangs up (or at least takes a long, long time to respond) when I do a search. It typically happens when I am searching by category and city vicinity. When it gets to the point of "List", it will take several minutes to respond, but eventually displays the list.

Is this a common symptom with others, or should I redo the upgrade process?
