Unfortunately, that modified version of DoubleCommand does not work properly. I have been down that path and many others with no success.
Can you be more specific as to the problem you experienced with the modified DoubleCommand? Maybe it's something that I can fix.
All seems well now, I think that the issue previously had to do with the assortment of other keyboard remapping software that I had installed. I went through and cleaned everything out and now it is working! I have only been using it for a few minutes, hopefully all will continue working.
Wow, bliss... Deck and Mac...
