On a related note, I just sort of got bit by the problem you describe. I just wrote a
little worksheet talking about Lagrange polynomials for my numerical analysis class. In
editing this worksheet on a Sage 4.3.1 notebook, at one point, I edited a paragraph of
TinyMCE text and when I saved the changes, the cell was replaced with a code cell
containing my new text in<p></p> markers. I deleted the code cell and created
a new text cell with the new text, so the text now looks like I want.
Just now, I saved the worksheet and uploaded it to sagenb.org. To my surprise, that text
cell that gave me problems was the *old* version of the text, and the new version of the
text is down at the very bottom of the worksheet! The sagenb.org worksheet is here:
http://sagenb.org/home/pub/1629. The paragraph in question is the paragraph talking
about Sage evaluates polynomials using an extension of Horner's form (just search for
"Horner" to see the old and new paragraph).
Nothing else in the worksheet was amiss.
I'm not happy that this happened to you, but at least I'm not alone now.

Okay, I just opened up the worksheet I mentioned above on sagenb.org,
and pulled up FireBug, and tried adding a few text cells to the top of
the worksheet. One of these text cells turned into a code cell when I
saved changes. From Firebug, here was the communication with the server:
