Troubles with cubase 5.5.3 since os x 10.6.8


i updated os x for v 10.6.8 yesterday and now, sometimes i get troubles when i launch a project in cubase…

it appear when i open a project for the fist time since a reboot of the mac

cubase close by itself and i must ignore and launch the app again for it works fine…

it appear at the moment when i sync my 01v92v2 and my project

somebody get an idea?
