weird MBOX fluke 3 times now.

[Eddie K. wannabe]

So i just got a MBox to use in conjuction with my digi001. Everythings been great so far. I got it friday along with a new 700Mhz ibook, in an hour i had the ibook up and running and successfuly transfered my digi001 files (Via firewire)to the ibook, open the sessions and evrythings great. In case your wondering how performance was, i can get 24 tracks and at least 8 plugins before i start to notice any system fatigue. (brand new ibook with nothing installed except protols and maxed out just for protools). I'm one happy consumer when i notice something a little weird. When i start the computer with the mbox pluged in, i open a PT session and hit play, i get a crackling sound and no distinguishable audio. So i disconnect and then re-connect the mbox USB and the problems gone. What up digi? Am i doing something wrong please help, not a big problem but I thought i'd post it. BTW I love my Mbox
