Windows 7 Trouble with vhosts in WAMP

Ok, I've searched far and wide (mostly in forums relating to WAMP and APACHE), but I suspect this is related to Win7, so I thought I'd try here.

I've used WAMP for several years, with several vhosts set up on development machines using WinXP, then Vista, and now Win7. This *same* setup worked fine in XP and Vista, but I can't get it to work in Win7 (which is why I'm trying this forum). In this case, I installed WAMP on my new Win7 laptop and copied httpd.conf and httpd-vhosts.conf over from my other laptop running Vista. All versions used in WAMP are the same on both machines. And, of course, I set up the Windows "hosts" file the same also.

I didn't want to post the long httpd file here (unless someone asks for it), but here are my hosts and httpd-vhosts.conf files:

Someone in another forum said I should have all my vhosts in the C:/wamp/www folder, but I don't want to structure it that way. And, as I said, this setup was working fine in XP and Vista, so I'm really hoping to do it in Win7 as well.

I hope someone can help. I've tried so many different things from suggestions in other forums, I really don't know what else to try.
