I'm running v12.10 on a Win10 Pro 64 bit PC. My video card is an Nvidia Quadro P2000. I have two monitors. My primary monitor is set to 2560x1440 resolution. My second monitor is set to 1920x1200.
I have a vertical two-lister layout saved that has been my primary layout for some time and has worked perfectly until yesterday. The listers are evenly divided down the middle of the screen. Until yesterday I could open it on either monitor, or drag it between monitors, and the lister adjusted to the resolution of the monitor, with the right and left listers each occupying half of the screen. But as of sometime yesterday, if I open the lister on my secondary monitor, the left side lister occupies about 2/3 of the screen and the right side lister occupies about 1/3. If I drag that list to the primary monitor it lays out perfectly with each side taking half of the screen.
I tried adjusting the layout on the secondary monitor to be evenly split, but when I drag that lister to the primary monitor, the left side takes about 1/3 and the right side takes about 2/3 of the screen.
I've tried unchecking the box "Open layout relative to the monitor the mouse is currently on" but that setting doesn't have any effect on this problem.
I've tried restoring older layout backups, with and without selecting "replace existing configuration entirely" but the problem persists.
Any suggestions would be much appreciated!
