Trouble with logging into to secure wireless hotspots

I'm running the pre RC-1 code on a Toshiba R-15 tablet.

Life it good in general. Loggin into open wireless hotpots is smooth. But
when I try to log on to a secure wireless hotspot, the connection fails to
authenticate. It looks like it's about to make the hook, but then pops to
the "cannot connect" error message. Feels like a new security setting in
Windows or IE is not allowing this connection.

I'll contact the hotpot admin to let him know Vista may have issue with this
login proceedure, but does anyone have suggestions for pulling back a little
on security when making this kind of connection.

Thanks

Dan
