Question : Cisco WLC web-auth - Vista authentication problem

We are running a cisco WLC 4402 in a environment mixed with windows xp and windows vista.
Lately we have had loads of reports from users with windows vista not being able not log on to our wireless network with web-authentication.
The web-auth we use is the standard one on the WLC, with a cisco ACS radius-server taking care of the authentication.
The XP users has no problem, and some of the vista users are ok, but the major part of the vista users just get the "Cisco authentication.." in the internet explorer toolbar, and that's it. After a while they get "cannot find page" or something in the main window.

Has anyone experienced the same? Can this have something to do with settings in internet explorer? It is the same problem with both IE7 and IE8.
