This has become an issue only in the couple of months leading up to warhammer and now its effecting warhammer too. In Shogun, Rome 2, and now Warhammer I have been unable to double click on units in the roster screen to get them in my army. I can still click and drag these units into the army but I cannot double click to move them or double click to remove them from the army. Double click works in every other program or game on my PC so this seems to be a problem with my Total War games. Any help is appreciated as this makes selecting an army for multiplayer and custom battle cumbersome and frustrating. Thank you!
