Ok, this is kind of broken

I noticed a really strange idiosyncrasy/broken system today.

I'm running Windows XP Professional, I'll use some screenshots to demonstrate what I'm talking about:

Let's say I'm connected to a network, in this example it's my home network, and I want to disconnect from it. I highlight it in the list of available networks and click 'Disconnect' in the lower right hand corner of the window. I get the following dialog box: (click to view full and escape the horrors of compression)


So I click 'Yes' - makes sense so far, Windows disconnects from the network and all is well.

However, if I get into the advanced properties dialog for this connection and then select the appropriate network and click "Properties" and then finally move over to the "Connection" tab, I see the following: (again, click to view full)


Ok, somebody explain this to me... according to my earlier choice I'm not going to automatically connect to this network anymore, and in fact it DOESN'T automatically connect to this network. So why in the WORLD is this checkbox checked?

Am I just stupid and misunderstanding this? (Not beyond belief) If anyone has a sane explanation for this - please, comment, I'm listening. :-)

Maybe it's just life with Microsoft products, eh?
