Audio Triggering + Mouse Event latency

[Bob Sneidar]

On that note, I remember reporting that in certain situations a fast mouse click was not seen by (then) RunRev. They are probably related. BTW, do you have any kind of virtual machine software running? It occurs to me that if something like Parallels is running, they install special drivers in the Mac to interface the keyboard with the guest os'es. Nuther shot in the dark. 

You may be dealing with interrupt priorities. I would poke around in Google and see if there is any way to up the ante on mouse event priorities. Of course, that would mean making modifications to the OS which is not ideal for a commercial application.
