Okay, after much text-widget-disappearing after upgrading to 2.5, here's what seems to be happening. When I have two text widgets in a row, when I go to edit the second one and save, it completely wipes the first one. If I go back and fix the first one, it wipes the second one. In essence, I have to have an empty text widget in between two populated text widgets in order to get them to keep their text.
Is anyone else having this issue? Any suggestions would be greatly appreciated, because I think I'm going to have to figure out how to roll back to 2.3.3 if I don't get this working properly.
