s thumbnails taskbar properties greyed out

Hi ... I have performed a few installations of Beta 2 now ... and on one I find this setting is greyed out and I cannot enable it.
I have just installed Beta 2 on my laptop and not only is this setting enabled, but I can change it as well ...
Any ideas why it would be greyed out and switched off by default???
Naturally I am in the Admin group so perms should not be the problem.
Cheers
Nick

Thats because you are running a Video card that does not support the Windows AERO Glass theme. I don't get the new Windows Vista AERO Glass user interface, why? Windows AERO Glass requires that you have a minimum of 64 MBs video RAM that is Direct X 9 compliant and supports the Windows Display Driver Model (WDDM), formerly (LDDM). If your video card does not meet these requirements, it's the likely cause why you are not seeing it. For onboard/integrated cards, you need to have 1 GB of dual channel memory installed with 512 MBs of RAM allocated to the system. The amount of Video RAM also determines the resolution size your Display can use.
To find out if your card supports AERO, click Start > Control Panel > (set to Classic View) > double click Device Manager > expand Display Adapters > if your card does not have (WDDM) beside it, its not supported. -- Andre Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta

I have a 128Mb nVidia GeForce FX 5500 ... and it has WDDM next to it in the display properties you suggest.
I also have 1.5Gb RAM.
Any other suggestions??

I found what it was. In the "Visual Appearance" section it was set to Windows Vista Basic, instead of Windows Vista AERO.
I changed this and am now able to activate the "Show Thumbnails".
