This post is a consecuence of some behaviors noticed in the menu after achieving the right-side scrollbar placement in a framed environment, as shown in my previous post.
Foreword: For explaining this problem I assume a MSIE 5.5+ as a client, and this web page as example for showing the issues.
The problem is the incorrect display of the menu items in the "body frame" for 2 situations:
1) When some scroll has been done in the "side frame" scrollbar
2) When accessing the menu for a 2nd or 3rd level in a horizontal menu ("header frame") who uses "divides"
In both cases, the menu items for the "body frame" appears vertically biased, since they lack of an offset adjustment or similar mechanism

It's not important for the example to work for the 2 orientations at the same time. An offset correction for each orientation separately would be perfect.
