Initially I was using 1920x1080, with magnification set 150%. The FE screen took up maybe 75% of the screen, and the mouseclicks did not lined up with the buttons.
Everything worked fine when I changed the magnification to 100%.
So, is there a way that I can do this without keep changing the magnification between 100% (when I am playing) and 150% (when I am not playing)? Thanks!
