Greetings all,
It the course of all my hacking today, I've managed to assemble a test case
that shows some sort of layout rendering bug. Clicking on the "preview"
column in the test case should hide the "editor" and show a second preview
column, suitable for printing. The editor hide()s properly, and the second
preview show()s up, but instead of being on the left side of the browser, they
are on the right. Firebug leads me to believe that the editor is hiding its
content, but still somehow taking up space.
Thanks,
Mike
