When I am on a thread and want to back up to the last page viewed and click the back arrow I have to do it 5 times before the page will back up.
Each click seems to try to take me something addressed as
http://googleleads.g.doubleclick.net/pagead/drt/s?tv=r numbers of some sort,,,,,,,,,,
I can see this by right clicking on the back arrow. It adds one more of the above for each left click. On the fifth click I finally get to the previous page.
If I just right click the arrow and then pick out the previous page from the pull down list, it seems to work. I don't think this is right. Is it something I don't have set up right on my machine??
