So, I went to edit the accompanying text for a slideshow of mine, and, after submitting my changes, *all* of the text was gone.

I figured that I'd just messed up somewhere in the process, so I went back and added all of the original text back again.
Submit.
No text with the entry.

Ok, so maybe the problem was with my Linux/Firefox setup.  I switched over to Mac/Firefox.
Entered in the text again.
Submit.
No text with the entry.

Mac/Safari?
Entered in the text again.
Submit.
No text with the entry.

So... is there any way that I can add text to my slideshow again?  I would really like to do so.
For reference, this is the slideshow in question:

Thanks!
