Yesterday during the rehearsal i´ve got a kind of "blue screen / white screen" with my mp-201

the display was only lightend, but without any Information or function. A reboot didn´t help.
the mp201 was conected via usb to my apple powerbook, and the 201 was in the quad mode.
i´ve disconnected the usb and restarted the mac and the mp201 again. nothing happens. after 10 minutes the mp201 started again with full display, but the mp201 midi-driver wasn´t found on my powerbook from now on.
it takes again 3 reboots to get everything in fully working order :-/
i´m wondering if the os of the mp201 is ready for live use???
any thoughts?
