White on white text, no drag-and-drop-widgets, fresh install

Hi, all,

I’ve seen this problem around and tried a number of solutions to no avail, so maybe someone has a fresh perspective? Here are the symptoms:

–can’t drag and drop widgets, nor can I drop down the “Screen Options” menu to change that to accessibility mode (drop-down on the header menus doesn’t work at all although it works fine in the menus on the left).

–if I try to add new pages or posts, any text I type or paste comes out white on white in the text editor boxes.

I’m running WP 3.0.1, and I’m also running Thesis 1.8. According to the web host, the server is Windows 2008. Here’s what I’ve tried so far without luck:
–disabling plugins
–adding the “Use Google Libraries” plugin
–deleting Thesis
–changing to the Default theme

Any other suggestions? Any help would be greatly appreciated!
