Likewise, been using Wamp for a couple of years now on my old XP machine. Got a brand new PC on Monday with Vista 64 bit on - so we're talking completely fresh and clean install. Installed Wamp..
It runs fine, can load localhost, firewall is not blocking, and I can see the systray icon - and hovering over the systray icon the "popup" tooltip works saying "All service running". But any attempt to left/right click on this results in nothing happening - no menus or anything come up.
Thanks for the XAMPP alternative suggestion, aszlej - I will use that as a "temporary alternative" until WAMP is fixed for Vista 64 bit
