I've only been able to find one other app that uses TXNSetCommandEventSupport(): <http://developer.apple.com/samplecode/ HITextViewDemo/listing12.html>. Unfortunately, it also crashes on double click :-( So, either the author is making the same mistake as me or it's a bug in this new API. I've forwarded the crash report (for the above app) to Apple.
