I can confirm this in FF7 as well as IE8. In FF7, I tried activating autogrow on a few fields. This worked as expected when creating new pages; however, upon editing existing pages with moderate amounts of text, the field was out of control. For instance, a field that had about 50 lines of text, the field actually loaded with about 150 rows, 100 of which were empty.

I believe I just fixed this in SVN. The issue was that the default width for textareas changed from 80 columns to "100%" - i.e., a pixel width instead of a character width - and the autogrow Javascript couldn't handle that correctly. I changed the default width to be a columns value again, if autogrow is set, and now it seems to be working fine.
