Media uploader not working in Wordpress?

Actually, after upgrading to version 3.3.1, I have Media Uploader remains the same (that is, without the possibility of simply dragging and dropping files) and when clicking on "Select files" nothing happens.

Tried to disable plugins, upgrade the engine to no avail.

This unpleasant phenomenon on two projects.

Can someone tell me what!?

Thank you.

And browser for what? I have Opera periodically is buggy, some features of WP. In one of the previous versions of Opera did not even edit the PHP template files directly from admin area.

Updated manually or automatically?

I had a problem when in the theme I connected with some Java script.
1. disable all plugins and check
2. if not helped to put the default theme (twentyelevn) and check.
