Tbird 115.3.0--can't adjust column widths; can't make Subject wide enuf; Date col waaaay too big
Just upgraded from Tbird 102.15.1 to 115.3.0 running Mac Studio (2022) Apple M1 Max, Monterey v12.6.3 For columns I use: Subject | Attachments | Starred | From | Recipient | Date | Spam | Size
No longer can adjust column widths as have always been able to do previously. Subject column width will not go wider than about one-fifth of Tbird window width; dragging handle goes to almost one-third width but once released, snaps back to about one-fifth of window width. Date column width will not go smaller than about one-third of window width. Can still shrink From | Recipient columns however doing so only increases Date to be about HALF of Tbird window width.
115.3.0 breaks Tbird for me. Thinking I need to go back to 102.15.1 via Time Machine unless this bug can be identified and addressed.
Thanks for any help.
