Windows Vista edit with Microsoft Office Word

[PamelaR]

I am running Vista, IE7, and Office 2007. I maintain a website where I am used to editing the pages by selecting "File-Edit With Microsoft Office Word" from the IE menu. Then I enter my password, edit the page and do "File - Save As Webpage". This worked fine on my XP machine with Office 2003. Now when I do that in Vista, it opens Word but never loads my page, prompts for my password, etc. So, basically, I can not edit my web pages on my Vista machine. I have been unable to find a work around, root cause, etc. Any ideas?
