<p>I'm running RT-3.6.7 on a Gentoo box, and have just successfully upgraded from 3.4.5.</p>
<p> </p>
<p>The issue we are having is with the Query Builder. When you do a search using the query builder, it works fine and shows the results page. From here you click on a ticket which takes you to the correct ticket.</p>
<p> </p>
<p>The problem is, when you click the back button at this point in IE, it takes you back to a 'Webpage has expired' message. Clicking refresh on this page warns you about re-submitting form data, and if you click OK, you get the list of results back again.</p>
<p> </p>
<p>The back function works as expected when used under Firefox, on the same machine.</p>
<p> </p>
<p>I've done a bit of searching and came across the MS KB article, and tried the fix presented here for unticking the 'Don't cache encrypted pages' option, but found that this option was already unchecked on my machine.</p>
<p> </p>
<p>Has anyone experience this before, or know a fix for it.</p>
<p> </p>
<p>Regards,</p>
<p> </p>
