I only had issues with (OS X 10.6.8, Logic 9) :
- Fielding DSP - Reviver
- eaReckon - EARbound
- Audio Damage - Discord V3
- TriTone Digital - ColorTone PRO & RecallTone
- Wave Machine Labs - Drumagog
- iZotope - Stutter Edit
Other than that it works great on all my other plug-ins.
And finally I can de-select all the PowerCore and UAD titles I
didn't purchase. The sub-grouping possibility is very handy as well!
