I am having a strange issue where occaisionally, a line of text in a post will overflow beyond the border of the main post area, and extend into the sidebar, instead of wrapping like it is supposed to. This is not happening on every line, and it isn't happening with every post - just sometimes. It even fixed itself magically in one post the other day. It happends in different browsers.
Here is an example of one place where it is still happening:
See how the text sneaks under the sidebar in the third paragraph?
I made this theme using the theme generator, which makes use of the YUI grid-fonts-reset.css
I also use the Advanced Tiny MCE plugin.
Any ideas? Thanks.
