he is using Infusion and I dont recall why, but i set the blocks to a static width for some reason. Your portal_page_header.tpl should have this line in it
<table width="150" cellpadding="5" cellspacing="0" border="0"
In order to have acp control like Mike is refering to, you will have to replace it with this
<table width="100%" cellpadding="5" cellspacing="0" border="0"
for the right blocks you will find similar code in the right blocks section of Infusion/layout/portal_body.tpl
if it distorts the blocks, go to ACP and set the header and footer sizes to 150 and it should look like it does now
