Sidebar widgets

HI,
when I log in and head over to the appearance >widgets section it loads up everything fine, yet I can’t edit anything, move anything or even add anything to my sidebar. I deactivate all my plugins and even changed my theme to default and still can’t do anything to them. Is any one having this same problem? I have not changed anything in the main wordpress download but it seems like it isn’t my theme or plugins doing anything funky. If anyone has any ideas I’ll be greatly appreciated.

Thanks for the support and hopefully quick response,

Aaron
