Tried searching for a solution to this problem, but couldn't find an answer based on the key words I was using...
Regardless in Quick Combat, Single Missions, or Campaigns and regardless if I reset keyboard defaults, use combat key commands (A, R, H, S) or FS/CFS1 commands (SHIFT+7, etc), I cannot get my wingmen to respond when pushing the relevant key commands.
Nor does the text appear on screen.
It had in past, but for some reason it stopped and I cannot figure out why.
