Make a line plot with Long Name string very very long.
Open Plot Setup dialog. ==> It took a few seconds to see the contents in bottom panel.
Try some actions on dialog, like click Layer 1 line in the bottom panel. ==> It took a few seconds to see the line selected.
Check Y checkbox for col C in middle panel, click Add button. ==> It took a few seconds to see bottom panel updated.
Check the middle panel. ==> column width of “Long Name“ or “Comments“ is very long, which is not necessary.
Fixed in Origin2024b.
