Hi, I'm having an odd problem that I haven't been able to solve with google and forum searching. Sometimes when viewing my wiki with unix firefox (I've tried with various versions--1.5, 2.16, and 3.0) the page is unformatted; it looks like the css isn't being applied. I'm using monobook, but the problem happens under different themes as well. I've never seen this problem on windows firefox or IE. Clearing firefox's cache and reloading fixes the problem. Has anyone heard of this happening? I'm using mediawiki 1.13.2, php 5.2.4, mysql 5.0.45, apache 2.2.6. Thanks, Peter
