Oooh maps! I like maps. I've a plan for some online mappery sometime this year myself, but nothing similar to this. Anyway...
I'm guessing the "SELECT * FROM.... etc" is the actual query you're running? If so, I think you ought to switch to parameterised queries, to make sure someone searching for that famous Corbett 'Ben Drop Table' doesn't cause any problems .
Layout looks better in IE9 than in Chrome (layout probs like CP describes) - search works in Chrome, but in IE9 it isn't working for me. In fact when I load the page, it shows the search splash window and none of the buttons do owt.
Would it be possible to synchronise the zoom and scroll on the two side by side maps?
