Web view category problem

Since we migrated to an R6 server, a strange thing is occuring to our web pages that contain categorized views. If you expand a category, click on a link that opens a pdf file in the parent browser and then click Back once on the bowser…the category collapses instead of remaining expanded (which would give you the option to click on a different link within the same categtory). Another thing I should point out is that this is only happening if we go through Policy Director to the site. If we use the Domino servers DNS entry as the web address, expanding a category, clicking on the document link and then back on the browser, takes you back to the expanded category. I don’t know if it’s a PD thing or a Notes setting somewhere. Has anyone else experienced this?

Thanks,

Ralph
