Hi
I think this may have been in a previous version too, but just updated to the latest beta 6.90 RC5 and everything runs smoothly - until I hit the throttle. After that the whole program runs sluggishly, trying to do lots of things gets fade out and occasional "not responding". The only thing that recently changed was I moved to a VM... As I said, not sure exactly when it started because I don't always us the throttle.
Regards
bj
