Howdy, I'm running Sound Designer II on a PPC 8100/80, running OS7.5 with 136 Meg of RAM. My files play back fine, editing works as it should. The problem is that when I try to record from the digital inputs the application locks up after about two minutes. The cursor still moves but I can't select anything and the input meters are frozen. When I try to force quit the hand appears, the fingers wiggle, and when I select "Force Quit" I get an error message about the floating-point co-processor which shimmers. I'm forced to restart the Mac from the keyboard. Any help will be much appreciated.
