with WP3.5 and Internet Explorer 9 it is not working on my computer. While being on the edit post page I am unable to insert images into the post. Clicking on the add media button above the WYSIWYG editor does not work any longer. Nothing happens. When I disable the plugin, everything is working fine again. I have Flash Player 11 installed.
Thanks for help
By the way: Could you disable the settings, when globals on Multisite are set? Otherwise, the settings and the note in the media are confusing.
