It is completely possible that the newer builds of Safari automatically block the vibrant popups. I only tried the Windows version long enough to know it didn't meet my needs so I can't actually verify that. I did a quick Google search on "vibrant popups Safari" and found a lot of Mac users complaining about the ads but not much from Windows users (not surprising as Safari isn't a major player on the platform right now).
That's because Safari for Windows really sucks! It crashes pretty much every day, but I still use it because I like it better over all that IE8. I tried the beta for next generation of IE and I had to go into safe mode to delete it!
