Hi,
So I have used the same keyboard with FA & FAF and not had this problem before.
When I am in game the Ctrl+1 to 5 keys are not working correctly, they seem to be doing other things than creating groups. When I go to key bindings and the group 1 key binding and type Ctrl+1 it actually enters Ctrl+V! But the Ctrl+6 to 0 works fine for grouping units.
Now it did have my keyboard language as CS but have changed this to US and in the FAF client, my Windows language is UK so not sure if this has something to do with it.
So I am limited to only being able to use 5 unit groups and it is getting really annoying, please help!
