I've come across the same problem. Despite having up to date software, including Nvidia drivers and Windows updates, I was getting the black dialog box problem on my Windows 7 Pro 64bit setup on both 32 and 64bit versions of AliasStudio 2010. It was all the more confusing since I was running on a workstation certified graphics card on the Dell Precision M6400 Covet laptop which should run Alias smoothly...
After what felt like trying everything, I tried disabling my Stardock Objectdock program and it solved the strange display error I was getting. My advice is that if you have a dock program like Objectdock or Rocketdock to disable it and see if that works.
