I am running Vista Home also and can not log into my yahoo mail; hotmail; gmail. IE 8 give me an "page unavailable message" each time I try to access any of those accounts.
i enter my email account information and it loops back to the logon page. i am using ie8, windows vista home version. the webpage is wildblue.net. i have tried compatability view and this does not solve. i have even tried one of the help pages and that page doesn't work. i have since fired ie and gone to google chrome. but i would like a solution to my problem. the wildblue page is partnered with google.
