Windows 7 - open multiple instances within the same website

I am using Windows 7 with IE 8 on a laptop with a second monitor. When I open a website e.g. http://www.co.benton.or.us/maps/bentonmaps.php and then open another instance within that site e.g. BentonMaps Tutorial, a new window opens and replaces the original and so on. I want to view the tutorial on one monitor while working the program e.g. Assessment Maps on the other. I tried changing the settings in the Folder Options/Managing pairs of web pages....., but that did not work. I am somewhat of a novice. The only way I can do it, is open a new session of the same site, but if I must take a break and work on something else, I have to start the process over, which wastes time. I should be able to open another instance from the original and keep that running. I have shortcuts to these pages (see screen shot below) but I cannot open them individually and view on both monitors. Very frustrating. There must be a setting that I have missed or maybe that particular site does not allow it, for I was able to open the link regarding screen shots here and move it to the other monitor. Appreciate your help.
Thanks,

As far as I know, Windows doesn't allow you to "assign" monitors to different functions. The four choices appear to be Duplicate, Extend, Desktop on one, Desktop on the other. So I think you want the "Extend" option, which makes your available display area bigger so that you can drag one window over to the other monitor.

Thanks for your reply. I have the "extend" selected. I talked to the tech at the Benton County GIS Dept. and he suggested that I right click and open the link in a new window. That worked great, so I think its been solved. Really appreciate your reply and suggestions.
