One other thing I might mention.....
I've noticed, and I don't understand why it would, but when I load the activity monitor, many times in the past (at least 30), VE/Cubase begin to become unstable (i.e. lock ups, White security box, etc.). I haven't been able to put my finger on it but I have found that for example, a problem will occur... I had the activity monitor up and running. Perform a reboot after a hang. Don't load the activity monitor and everything is ok. Load the activity monitor to see where my memory is at and things start to again become unstable.
This has happen several times although I can't seem to get it to repeat itself on a regular basis.
Not sure if any of the VSL team or any of the users have experienced the same. Don't want to send anyone on a wild goose chase, but I thought I'd throw it out there.........
