Text Editor Woes

Hello,

I have a problem with the text editor, in that it likes to wrap paragraphs in divs on occasion, seemingly at random.

Most recently I spotted it in a paragraph after an unordered list that I had created. It also just happened when I inserted some italicized text before a paragraph.

Does anyone know why this happens, and how it can be fixed? It is rather infuriating, as the end result is no white space after the end of a paragraph. I have to go into the HTML editor and manually remove the divs.

Cheers,

Tom
