I've previously posted error reports (with logs) both in alpha & again in Beta 10 re: pronunciation causing a crash. Apparently it was decided this was an OSX 10.5 problem which has been fixed in Beta 11 but the fix seems to have included the removal of the pronunciation button from the Information tab. How do I now get pronunciation of a word?
You can use the Pronunciation panel or the pronunciation buttons show in the Word by Word section in guides. This seems to be regression in Beta 11.
