Just in case this affects anyone else:

I'm not sure if this is only on my site but I noticed the "Search for Place on Map" option was not working when I had the Yahoo GeoPlanet (all round place search) selected. This was on all data entry forms. I think it did work in the past. Firebug didn't show any errors. It works correctly with Google Places API text search so it's no big deal to fix if you know about it!
