Has there ever been a resolution to this problem? I’m running into the same problem.
I’m on a Mac OS X 10.5.8. Firefox browser. Also having the problem on Media > Add New page, and when I have the WP e-commerce cart plugin I have a similar problem on the Store > Products page.
The weird part is that on a PC (XP, Firefox and IE) the only page having this problem is the Permalinks page.
Thank you,
Jeff
