I have upgraded to Wordpress 3.5 and find that the standard Insert Media and Featured Image post functions do not work. I have tried deactivating all plugins but this does not fix the problem.

Is anyone else having this problem?

try swapping to twenty-eleven and see if they work

Thanks. After a quick panic I found the issue - and a fix.
