One thing about this so called 'lock down' is a sense of irrelevance when it comes to time !! Anyway, passing the time doing rather nothing, many of us have experienced this hang when loading the game and it doesn't load, it just hangs with the DCS black screen etc, sound familiar ? Well, it is when you tick the box in options 'Full screen' the game won't start.
Go into options (located in 'Save games' DCS Open beta\config\options) and scroll down to 'Graphics' where you will see 'Full screen' marked as 'true'. Simply change it to 'false' and it's all fine and dandy, you will be home for tea and cakes and flying your next imaginary Top Gun mission quicker than you can say 'CoronaVirus' !!
My support ticket suggested this problem is related to antivirus software and firewall problems, it's not, it appears there is a problem in the options element programme where 'Full screen' option is null and not working.
Anyway, I have got back into modding DCS and it's been fun finding the fault.
Keep safe and well everyone.
