Premiere Beta (release 30) Crashes often

Hello!

I’m not sure if this is the right forum for a bug report on the beta release of Premiere, but it seems that the latest build (build 30) crashes much more often in the color panel than the earlier builds did.  This could be due to my getting more comfortable, and therefore ambitious, with the new toolset.  Now when I apply a mask (rectangle or oval) and try to track it, the program locks up almost every time.  

If this needs to go to another fourm, please let me know.

Thanks!
