Issue with Amazon.com redirects and back button which Bypass fixes

[MR_yeoman]

Using: Proxomitron 4.5 with no special config sets, IE 8, SandboxIE, Windows 7.

Hi, I have been using The Proxomitron for years and have finally run into an issue I can't write my own filter for, or at least don't know where to start. The problem is with Amazon. If I click a product, it goes to that page, but then my back button does nothing, I can't get back to the original page without clicking the history arrow and selecting the page I want. What happens is there are two interim pages that don't let me go back past them. For example from the front page I click on a drill my history will show:

Amazon.com: DEWALT DC742KA Cordless 12-
http://www.amazon.com/aan/2009-09-09/st
http://www.amazon.com/aan/2009-09-09/st
Amazon.com: Online Shopping for Electro

Then to go back I have to select in history the entry before the two /aan/ pages. If I bypass proxomitron then the problem doesn't happen, in fact the two /aan/ pages don't ever show up in my history. I've also cleaned cookies and other simple browser tricks. If I look at the log window nothing comes up with /aan/ in it.
Anyone have any ideas? Anyone else have this issue?
