I’m seeing the same problem here, with 3.2.0.1. Basically once a file is uploaded you cannot replace it or modify any properties from the WordPress Admin pages. This is pretty fundamental.

Not sure I understand the file browser workaround : When I view files via the admin file browser and click Edit I have exactly the same problem.

Is it safe to downgrade from 3.2.0.1???
