A quiet day and I was playing with CCDStack in 64bit Win 7 Pro which I just upgraded, so I did a repro version of my recent M83.
Having 4GB of real RAM available to CCStack makes a huge difference

. things that took 5 mins now take <5secs so I'm glad I made the jump. Also makes a big difference to PS3!
Lots of issues though with DSI drivers that needed heaps of tinkering in the XP Mode that comes with the Pro version, but it all seems to be working now.
The scale is slightly different in the two - I was more looking to improve technique. Let me know what you think.
