Crashing Problems?

I was searching for a program similar to After Effects and Final Cut Pro and I was about to give up. But then I found Motion! I loved it, I was able to make school projects and short home videos. But now, everytime I try to use the Belzier tool, it "quits unexpectedly" and I have to reopen it. But then it crashes again! Please fix in new update, and if there isnt one, make one! Apple Motion is simple to use and easy to learn, but it just has a few bugs. Please fix soon.
