"take over settings from internet Explorer" does not work

Setting "take over settings from Interenet Explorer" does not work. I believe the proxy IS set to the default proxy in the system, but authentication does not happen automatically as it would happen in IE.
System.Web and the like let you say you want to use the same proxy but in fact the don't automatically take over your credentials for authenticating you... IE "cheats" in this I believe :-)
So I am not sure about the details, but in case that cannot work and you have to specifically set a proxy for the application, then it should AT LEAST be explained/written in the GUI, I believe.
