Does anyone have any suggestions?
More detail would be appreciated. Are you on Mac Sonoma beta?
Is the black panel present when you open a Search from the toolbar?
Does it work with a wider panel e.g. open in a floating window?
I am using Monterrey on this particular machine.
Yes, the black panel is present when opening the search window.
I get the same result with floating window.
I can use the search function in Bible pane, however.
I misspoke. The black panel is not present when opening the search. It appears when the search is attempted.
Does it work on the other machine? What version?
You might try updating this thread title with a prefix of BUG:
I will check the other machine, which is running Sonoma.
The problem does not replicate on the machine running Sonoma.
Interesting. But we'll leave it as a bug, because it should be OK on Monterey.
