As the title says, the Matchboard has stopped showing TM and glossary hits and keeps staying completely empty. There are no other Matchboard instances open anywhere (as far as I can see).
What may I have accidentally done to stop it from working?
Update: the Matchboard shows only TM hits, not glossary hits, which I can clearly see in the glossary panes.
Either righ-click at the specific glossary pane and make sure the "Keep out of auto-assembling" option is not checked, or right-click at the Matchboard and check your settings for showing fuzzy glossary terms there.
Thank you Igor. "Keep out of auto-assembling" was not checked, but the Matchboard was not set to display fuzzy glossary terms.
