I have been using VW 2.6.0 and noticed pops when selecting tracks which are part of a "track stack" in Logic Pro X (10.2.1). The pops are absent when a different track is selected (one outside the track stack) and I do not think therefore it is simply CPU overload.

I tried to upgrade to v2.7 to see if it made a difference but the AU won't open in Logic X - the manager says the plugin is unable to load and it will not prompt for authorisation.

I can authorise it in Ableton and I have the latest PACE ILok programme (not dongle) which has my Mac authorised.

It's odd - any ideas on either of these problems?
