StoryboardPro crash twice

StoryboardPro crashed two times today.
The last time the whole project disappeared.
Luckily it was a new project and only2 hours of work got lost.
But this behavior make me uncomfortable.
There was recently an upgrade on the snowleopard, can it be something there?
Hope for some help to solve this.
Best regards

There are a variety of things that can cause crashes - usually a scene that is heavier than your computer can handle. What kind of graphics card are you using? If you continue to have crashes then you should contact tech support.

Hi Lilly
Sorry that I did`t see your reply before.
Think the problem have been sorted out.
Have seen some printer tips on the forum thats probably same cause.
Have had no more crashes as I can remember.
Thanks for the reply
