I have the steam version of ArmA II Op Arrowhead beta, with the call for support, and lost key installed. Everything is working like a charm, except for the command button. At times it works and other times it doesn't. I will start DaiZy and sometimes I'll be able to press space bar and get the commands up, which lets me command other friendly AI, but a lot of the times I can't access the commands. It's crazy, because I will exit DaiZy to the Main menu and access any other SP mission and I haven't had the problem, only DaiZy. Also, I know this next Q doesn't belong here, but do you have any other maps? Thanks in advance!
Yeah I think everyone has the same issue... The only work around I know, is to use the key that selects all of your units - it will bring up the same command options than pressing space bar.
And, yes, there're other maps in the release section, but some of them might be outdated atm.
