Since the latest Thunderbird update (128.4.2esr (64-bit)) in Ubuntu (Ubuntu 22.04.5 LTS Wayland), it no longer responds to hovering over *any* boundary of any pane. I've restarted Thunderbird, and I've rebooted the machine, but to no avail. Panes can't be resized -- not horizontally, and not vertically. It could be that the zone for resizing has been reduced to less than a pixel and that my low-res mouse in my aging hand just isn't precise enough to grab an edge. Is there an option somewhere to display easy-to-grab (and easy-to-see) handles on pane boundaries for those of us with old eyes, unsteady hands and crappy non-gamer mice? At the very least, I need a clear cursor change when "in the zone" for grabbing and dragging, otherwise I'm liable to grab an email message and drag it instead (with potential data loss). Thanks
