While using the WP editor, I hit the button to add an image, invoking the Add an Image dialog. On the From Computer tab, I hit Select Files, and select a file. That prompts a "crunching" prompt, but then the space in the dialog that normally shows parameters to set for the image, instead in a rather broken-looking way shows a WordPress logo and the form elements from the login dialog, overlayed with an href link "Back to [my blog name]"
This happens consistently. I've tried logging out and logging in, and I can edit and save the post just fine, but each time I try to insert an image I can't get this odd-looking login thing on the image upload dialog.
(I have a screen shot if anyone's interested).
The blog I need help with is grahamwideman.wordpress.com.
