I have upgraded my WP install to 3.7.1 - using Canvas (WooThemes) with Child theme. When I use Safari (7.0) and log into the admin screen everything is fine until I view the Canvas menu - it then freezes, so using Safari I cannot administer the theme options.
The theme options work fine in Firefox and Chrome, just not in Safari for some reason, and only since upgrading to 3.7.1
When I activate a standard theme such as Twenty Eleven - the dashboard when viewed in Safari works fine - all the navigation is fine..
It seems very strange. Just wondering if anyone else has encountered this?
