Several users reported that Delish crashes when generating thumbnails. I traced the issue to a race condition in the screenshot generating service.
Thank you to everyone that submitted crash reports, and thanks to an expedited review, Delish 2.1.2 is available now in the Mac App Store.
I had a hard time even reproducing it until I enabled multiple cpu cores in the 10.7 VMware instance. That did it, as it would crash within seconds of launching. Consistently – ouch.
