I've been using CDEX from the very first release. When the updates and newer versions stopped coming out I was disappointed but still found it to be the best one I could find even if I had to tweak it a bit to run properly. This new version is everything I had hoped for in a new release and seems to have solved all the issues caused by being out of date in the older versions.
Peter Grossman - I'm using it with Win7 pro SP1 32-bit and it works fine.
