Ty, now I understand. When you intially log on to Stunt Hangar, you have a choice of being connected for one session or forever (I think that's the default setting). That's a bit of a misnomer because you aren't really logged in when SH isn't open in your browser. What it means is that a cookie is stashed on your computer and when you select SH in your favorites, the browser, takes you to the website but you don't have to login each time. It appears that it's been open all the time but it isn't. The cookie does the log on work for you.
So the bottom line is that when Stunt Hangar isn't open in your browser, you aren't logged in.
Just in passing, if you decided to dump all of your old cookies (an option available in Internet Explorer) be sure you have all of your passwords. It requires a full login to every website you frequent.
