Don't be concerned, I do not take offense at your comments because they are most valid. You are correct in that we need to do a better job at capturing bugs like this before they get into a released product - especially regressions.
Remember that I was a customer for quite some time and so I empathize with you all. This is a major challenge for us as we continue to add functionality to our product for both the purpose of completing features, that are incomplete in their functionality, and offer new functions to help you get your jobs done.
Thanks for bring this to our attention.
