Crashes frequently

Macbook running 10.8.4 OSX. App repeatedly quits unexpectedly when in the process of stitching. To date I have completed 2 stitched panoramas and had 9 unexpected quits - first time for any unreliable app on my Macbook. The panoramas I am attempting are simple scenery stitches - 4-5 photos from a simple point and click digital camera. I have not tried anything from my SLR yet but will test that shortly. When it works it produces good results but it is frustrating to buy an app that has good promise but looks like it has not been subject to any detailed quality testing.
