When I create a new patch, change some thing properties, then close the app and choose to save the patch, I can save and quit the app as expected. What steps are needed to reproduce this?

It's unfortunately intermittent. Sometimes I get it, and sometimes I don't. I'll toy around with it and see if I can establish a repeatable pattern.
