this is the code (generated by tabPanel) that wraps a tab content:
<table class="dr-tbpnl-cntnt-pstn rich-tabpanel-content-position" cellspacing="0" cellpadding="10" border="0" width="100%" style="position: relative;">
it's style position:relative is the cause of IE do not render a div (tab content) with position: absolute in a proper way.
I cannot wrap this with a css class once it's directly on style attribute.
In other words what I want to be able to do is to absolute position an element with noninterference of tabPanel.
the code generated has the same effect with style="position:static" (simply not set) and it's more flexible once the user would be able to customize it.
My suggestion is to put position:relative in rich-tabpanel-content-position class
