the new Curve EQ does not work at all on my system. 10.8.2 (64 Bit).
You can only see the GUI react while you resize the plugin window. Since you cannot do this while you work it’s completely unusable on my system.
This is happening on a multi monitor setup (3 screens), I remember that this was an issue with other Voxengo stuff I own previously but it’s now fixed in these plugs.
