After several seconds of checking, I received a dialogue box stating that an important update, designed to improve performance, was available. I clicked on "Click Here" to get the update.
The update installer insisted that I shutdown VideoStudio Pro X3 before installation could begin. Once I had taken that step, the patch installed quickly without incident.
Sorry that I can't offer any insight as to what has been improved or changed as a brand new user. (This update was not an update to the SmartSound Quicktracks module supplied by SmartSound.)
Cheers,
Bob
