[SOLVED] Can't edit posts - edits vanish - Virus? Theme Issue? WP Issue?

OK I have a weird thing happening. http://www.eyeonannapolis.net

I typically will create a post in Word, copy to Wordpad to strip the coding and then past it into WordPress to create the post.

This morning, I did that and it pasted fine, but when I scheduled the post and hit PUBLISH the body of the post (text) disappeared. (sort of like if I had pasted white text on a white background). When the post publishes, all I get is the title.

If I preview, same thing.

Does anyone have any suggestions? Or directions to point me?

I am on the latest Atahualpa theme and this mornign when the problem first surfaced I was on WP 2.8.2 and it is still there after the upgrade to 2.8.3 this evening.

I am thinking along the lines of a virus (or a plugin gone wild) as I have another blog very similarly laid out with this theme and all.

Any direction anyone can point me to will be greatly appreciated!
