Victorina, I finally downloaded this and the software...using Explorer, installed software, and ran it....no problem. Someone else....can you make suggestions to V.? I have a 3 1/2 year old Dell laptop running Windows 2000.

I suppose you can just use Explorer...there is some requirement for graphics card on the viewer page....so if you have an ancient computer, maybe it is hopeless.

The ability to spn through this stuff is pretty good...I would think Roger would want to take a look if his computer is not too ancient......although I'm not sure I learned anything (although I guess I did not spend the time to look for internal structure.....
