not sure if this helps, but, my resolution is 1366x768, and i have this problem
however i tested this from a computer with higher resolution, and it didnt happen. i even checked if my mouse is the problem, so i went there and used my mouse, there was no problem (the reason why i tested the mouse is because in the past i had a few of them starting to double click on its own, so i suspected thats the case again, tho when i had this problem in the past, it was happening everywhere, not just in FoE)
my theory is that when on higher resolution, under the Back to city button, there is no GB, so this cant happen. on lower resolution, usually there is some GB behind the back to city button, so it happens because the mouse clicks in the background (i beleive this has something to do with harware Acceleration because we have all experienced background clicks since hardware acceleration)
