I just thought that I would inform the "powers that be" that there is a bug with vst~ when a pluggo plugin is loaded. This occurs in max 4.5.7 and pluggo 3.5.4 on Mac OS 10.3.9.
1) Create a basic vst~ patch and load a pluggo.
2) Turn audio on.
3) Open cycle~.help.
4) Click startwindow.
On my machine, nothing happens unless I reinitialize the dac~ by unlocking the patch and retyping dac~ into the object box.
Also, I would LOVE to be able to open the gui for a vst plugin as a floating window.
