WordPress 3.5 Problems

Anyone notice the new WordPress update that rolled in a few days ago?

It’s a pretty radical change and one that seems a hell of a lot better.

I really enjoyed using it for a day or two until the functionality totally broke. Is anyone else having problems with this?
Now if I try to upload images into a post the first image will start and then hang. I also cannot load the media library from inside the post. However, I can view my media library and upload things into the media library if I use the new Media section on the left hand toolbar. But I can’t put images inside my post!!

I’ve tried clearing browser caches and cookies to no avail. I’ve been scouring the internet for fixes and haven’t stumbled upon anything remotely helpful. What to do?!?!?

I want to keep on the blogging!

UPDATE – I should probably add that since I’m behind the Great Firewall of China I use a web based VPN service , Securitales , to access WordPress. This didn’t cause any major problems previously though.
