Unresponsive Script in GA release

This is the error I see whenever I start trying to edit pages (upgraded to 7.7). I can hit Continue and it works fine however.

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.
