Apologies if this is already answered elsewhere; couldn't find it if so.
Recently, for No Apparent Reason, all the free-text entry boxes in my Atahualpa theme options have become single-line height. The text is all there, but I can't see it, nor is there a resize handle in the bottom-right-hand corner anymore.
Any ideas? Running 3.5.1 on WP3.0; Firefox 3.6.8 and/or Safari 5.0.1.
