This originally happened with me in 6.3 RC 1 (when I switched from 6.2). See: https://community.logos.com/forums/t/104906.aspx
It inexplicably started working again for me in 6.3 RC 2 and for others in 6.3 SR-1. However, I never saw it mentioned in the release notes.
So, was this *officially* fixed or not? If it was fixed, was the fix left out of the 6.4 beta?
