Here is an example of my earlier post which I would like to stress again is not necessarily the answer to your problem.
Please visit this site:http://www.baseball-links.com/
A little way down the left hand side you will see a link to "Henderson finally signs with BoSox".
If you click on that link, then a new browser window is opened . In my case it opens this new window at 1/2 size, but this is not always the case, and were it to open in anyones browser at full size then they would hardly notice that they had moved on to a new browser window. If you were to move on from there via another link then your "back button" for sure would only show "one back".
Trust this might be of some help.
