Well I believe I've fixed this in my git tree, and I've uploaded an exe into that temp directory as always. If someone is brave enough to try the latest driver 12.2 with its sdk on 64 bit windows with this executable I'd be mighty grateful:

Awesome awesome, thanks. This is big enough a fix to warrant yet another quick release. How did it perform compared to the older sdk 2.6 ?
Just about even.
