9a) If yes, can you do it consistently: Yes it is constant

11) Any other notes regarding your setup only: All the tracks worked fine on my previous machine.  This is not a database import issue as i am testing using a selection of randomly imported tunes - approx 400 files, every one of which that has been tested will not drag to the CDJ

12) Provide as much detail of the issue here: Files will not drag to a linked cdj.  I had this issue with my vista install until i put the cdjs onto a standalone network controller card.  The separate card is not helping on the windows 7 install.

Further research has revealed that the new nic is based on a realtek chipset and there appears to be reported compatibility issues which remain unaddressed.
