Ross Rader lamented in his blog that MT Templates are Goofy. Although I think the issue is more one of IE's rendering engine being goofy, he hit on an issue I've been seeing (and which I had written off to some screwup I must have made in configuring Apache) — sometimes, for no apparent reason, the main page of my blog will only render in the browser up to the bottom of the links section on the right side.
Turns out this is due to a bug in IE6's rendering engine, and there's a quick workaround (which Ross found in this thread on the MT site). Just add the following right before the </BODY> tag:
<div style="clear:both;">© 2003 Eric Longman.</div>
This forces the page to render both columns completely.
Thanks for pointing me in the right direction, Ross!
