Don't click on a topic to change to that page. Instead, right-click on the topic and select "Open Link In New Tab". Your original forum list or search results will still be available in the original tab window. You can switch back and forth between tab windows as many times as you want to.
This works as does LedFowl's suggestion. For some reason the back arrow has no effect. Just switched to Win8 and I am sure this is operator error. Appreciate the help.
