I seem to be having an issue with WordPress 2.X on my system. The blog site http://www.rlhc.net/blog/ works fine under Firefox 1.5 but does not render the pages correctly under FF 1.0.X, IE 6.X, Galleon or others. Example, under IE the column where the blogroll and archives are are supposed to be are missing. Under FF 1.x the full list of the posts on the open page do not finish and the blogroll column is missing.
I have tried on several machines cleared my caches removed my proxy server reboot the server and updated to 2.0.1.
I use FF 1.5 so I have no idea how long this issue has been around.
