I'm using the Time Manager to control a servo for a device.
At the beginning of the interrupt routine, I call PrimeTask so that 
the program will be interrupted in another 10 msecs or so.  This works
fine, but occasionally I get a system crash due to the following
message:
	Unassigned interupt #$00D (format $09) at $411e8

Does anyone know why this would happen? Or where I should look to
solve the problem? (I'm using a Mac II). I know that the routine is
finishing before the next interrupt needs to be generated. Any help
would be appreciated. 
Thanx,
Steve Drucker
