I think it may be that the problem is related to Kontakt because it seems that as long as I dont use Kontakt in my older songs it seems to work fine and pro tools usage of the cpu is idling at 0.1%. When I load a song that uses Kontakt from before the Komplete 10 Ultimate installation Pro Tools idling is at about 60% of CPU.

Also, if I move a track, up one notch for example in the Edit Window in Pro Tools on a normal track it moves instantly but on one with the old Kontakt it takes around 20-30 seconds and uses around 70% of CPU. So it seems that Pro Tools might not be freezing completely but running extremely inefficient.

So on some old songs I don't use battery 3 and it still hangs, or maybe more correctly, crawls extremely slowly.
