FWIW it’s rather bizarre. If I go to the dashboard using the Site Admin link on the front page. The drop downs work. If I go to the dashboard via edit post, drop downs don’t work. Either way I can’t create new categories or add post tags as nothing works any more.
Fixed! saw this post:

just reload the frame in the blank popup and it works after that
Found the problem. In the plugin, I had to surround the functions with:
if ( !function_exists(‘wp_login’) ) :
…
endif;
and
if ( !function_exists(‘wp_setcookie’) ) :
…
endif;
you don’t need these function_exists checks in 2.0 in your plugin but you certainly need them in 2.2.1
OK, I found it:
Options -> Miscellaneous:
turn off:
Use Geographic Tracking Features
and keep it off!
