Just bought for iPad2 and hangs on chalk tool

[Siberartditto]

I rebooted and lost a piece I was working on but corrected the "hang". No memory low icon appeared when it froze. I hadn't done a whole lot so don't know why this would happen. Lead me to the answer if already asked please, or need a little help in how to prevent in future.

Great program and I use on Mac Book Pro with no problems.
