No matter what button I assign the Comms menu to, sometimes it doesn't work. For example, I could be several minutes into a mission, and the comms button doesn't work, but it would at the start of the mission. It doesn't matter what aircraft I fly. I can go whole missions without a problem, but others, it'll work at the start, but when I need to access the comms menu, nothing happens. I have even tried binding it to a different button on my HOTAS during missions, but nothing seems to work. I am using version 2.8 on Steam. A TM Warthog Throttle, and a Virpil Mongoose stick, if that helps.
