Hey Keystone...
Cool, you are right. This solves a big part of the problem. It does appear that the Mappoint link on each cache page first goes to the 'old' mappoint.msn.com site. Then if the site detects, that you are on a Windows computer (not Mac), and you are using Internet Explorer (not Firefox, Opera etc) then it will forward you to maps.live.com, *AND* it uses the direct coordinates, and pinpoints the cache location. You can then switch to birds eye view, and zoom in and there is your cache location.
I am still struggling to figure out how to enter some form of direct coordinates into the maps.live.com location bar. The reason why this is useful, is if you are doing a puzzle cache soluiton or the 2nd stage of a multi, and want to view it in maps.live.com, but you have the coords manually in hand, instead from a link on a cache page.
I can see in the maps.live.com URL itself, that results from the forwarding from mappoint, it seems to use the log/lat in "pure decimal" form. So no minutes or seconds, just degrees, with decimals. The geocaching site mainly uses the degree, and then minutes with the minute decimal. (no seconds)
I found that the Jeeep.com link (yes, 3 e's) listed on every cache page, will take you to a converter, that will give you the log/lat in all forms, including the pure decimal form.
However, no matter what I try so far, I can't figure out the syntax or exact format which will make the site happy with enter numerical decimal coords.
I also started to explore, the "Build you own URL" help file which poohstickz pointed me to. That does look like it should work to enter the pure decimal numbers into the URL syntax. However, after trying to enter some pure decimal coords into the URL, the way it describes, I am still getting other locations in other states than what I should.
I will keep poking at it. Anyone else feel free to poke your own sticks at it.
