When I try to open an old patch I get the error message:

error:can't fragload adc~(missing sys_getch>), err -2807

When I replace the adc-object with a new one and try to save the patch Max crashes.

I'am using Mac OS 4.7 on a PPC G 4 Alu Powerbook and an RME Fireface 400 Soundcard 

With MaxMsp 4.5.7 everything works fine...

I've just installed MaxMsp 4.6.2
