In some cases a new browser window is being opened.  Users frequently
don't notice this happening.  In those cases you can simply close the
new window, or return to the original, and then you can go further
back.  In other cases a bit of JavaScript such as this is being used:

<SCRIPT LANGUAGE="JavaScript">
<!--
parent.location.replace("http://www.acm.org/pubs/contents/journals/cacm/");
//-->
</SCRIPT>

There are other ways it can be done too. So, basically, in most cases
it is being done by the page on the server.

However, I've noticed a few cases where I've not been able to figure
out why it is happening....and some seem to be simply a problem of the
machine being about to crash, as after a reboot the problem isn't
replicated.
