As I recently found out, Vista Home Basic cannot support Transparency like xP due to it lacking the necessary WDDM drivers. Now, I'm no Tech-Wiz, but when ever I needed OTHER types of drivers for other programs to run on my PC, I was able to simply download and install them. So, (and please dont laugh if this sounds stupid, but) cant the WDDM drivers be copies or extracted from xP and then installed on Vista inorder to get transparency support for Windowblinds?
