It has been brought to my attention that SquawkBox 3 is listed on IVAO's website as "approved software". As I mentioned before, no work has gone into making SquawkBox 3 work on IVAO, it has not been reviewed by IVAO staff and as such it is not approved for running on IVAO.

If you want to use SquawkBox 3.0, you're going to have to do so on VATSIM.
