Actually there is no software that can guarantee to be more stable in new versions as long as there are new features in new versions.I don't understant I thought new versions would be more and more stable and not less so.... this is frustrating, because I loved this program.
I cant reproduce your problem here , maybe a clean install or deleting your chlist.chl and letting DD create a new one might help you. and you can always use the old versions if you are not happy with the new ones
