Anyone else getting a lot of crashes on Harmony Premium 12.1?

I’ve been getting a lot of crashes while using Harmony 12.
Here are my specs:

iMac 12-Inch, Late 2009
Processor 2.8 GHx Intel Core i7
Memory 8 GB 1067 MHz DDR3
Graphics ATI Radeon HD 4850 512 MB

Any idea why this keeps happening to me?
Thanks!

Your graphic card only has 512 MB of RAM, that’s not a lot to work with when
doing complex effects such as using the deformation tools, light table, onion skin…

Beyond that, try to get some details from thew crash report and look for the common factor.
