getting slurls to open the map

I am trying to make a slurl that causes the map to pop open within SL. When I click on a slurl, it sends me to slurl.com, and then when I click on teleport now, it opens up SL, but I have to click on the Map button and then click Teleport. For newer users, this is confusing and not ideal.

Here's an example:

Is this a problem with my browser or my SL settings, or is it something to do with the way the slurl is built? I saw one suggestion that I change the %20 to an underscore, but that didn't work.

thanks.

How about slurls and SL knowing you're already logged in?
