Bug pattern -- DO NOT REPORT MISSING HINTS (see mizinamo's post here)
The words starting with qaghwI' consistently have empty dictionary hints.
So far, doing ⌘F on the Klingon Dictionary seems to be working fine, but this should probably be looked at.
To add to that, and speaking not just to Arkadios200 but to anyone who may come across this discussion:
Please refrain from reporting "Hints are wrong or missing" for words starting with apostrophe -- as jdmcowan wrote, this is a general problem which is known and which will hopefully be fixed soon. Reporting a known issue will not make it any more known, nor will it fix it any quicker.
