CDJ850 HID & Cross

I purchased Cross 2.6 after giving up on Traktor ever supporting 850s in HID mode, and so far im pretty glad I did.
The software pretty much takes the cdj850s to a whole new level !!
My only gripe is that when first starting the deck/software up and selecting deck A or B they are sometimes swapped around so you have to go into Cross' setting and switch them over (annoying why cant it remember?). Also sometimes when I select a new track via the decks (or PC via mouse) the other deck stops playing, so I have to do a quick pause/play on the deck (not very stable for playing out).
The PC (whilst isnt state of the art) happily runs Traktor and other quite hungry applications OK - so can anyone advise what the cause may be?
