I just added [and "Apply View"] to this question. -mr Does "Apply columns" work in Tbird 115.12.2 (64-bit)? I searched 'Thunderbird Solutions' for "Apply columns", then read several of the 156 results, and read the Help Article "Message List Columns" ... but the results were [imo] not encouraging :-( Does "Apply columns to" really work as described in Help Article "Message List Columns" ? Is "Apply columns" a known flakey feature ?? Have I got a corrupted profile ??? Or ???? Thank you, --Mike Ramey
