focus problem

TonyRopson — Tue, 22 Nov 2011 18:38:05 GMT
Once the query task has been completed I am attempting to get the map to focus to a particular area which is at the 0 item in the parnums array. However that map appears to be focusing other elements in that array (I would say about 1 in 5 times give or take) and I am not sure why.
