[Ham-Mac] Cocoa modem locks up

[EZ Rhino]

Has anyone had issues with this?

When I first hit 'transmit' in PSK using CocoaModem 2.0, occasionally it will put the rig in TX mode, but not send any of my text, and then I get the pinwheel of death.  All the buttons in CM become locked up and it is impossible to un-key the radio unless I turn it off manually.  I have to choose 'Force Quit' to shut down CM; but that isn't enough.  I'm using the Cocoa PTT along with it, and it is impossible to force quit the Cocoa PTT; I have to shut down the computer and reboot to get it to shut off!  And if that's not bad enough, choosing 'restart' from the apple menu doesn't work because it cannot shut down the PTT application, I have to hold the power button on the back of the computer in to force the computer off.  Not the best scenario for a shut down.

Comments?
