As I said earlier, the stuttering is intermittent and I have just realized that it only starts to happen after I have played several songs after starting the program. It NEVER happens, even with the "bad" songs, the first couple of times I play those songs. This may sound strange but I have proved it with many tests.

With regard to your advice about de-selecting high speed generation I tried this and nothing changed. Since I always freeze all tracks you wouldn't expect generation to be an issue with this problem would you?
