Ah, bad formulation by me. While testing I had both the same machine and external machine sending UDP packages to the port I was listening to.

The listening server would not receive anything on 64/64bit (unless running from IDLE).

The reverse try, running the listening server (same program) on another computer, it would receive only from its own stream (while the 64/64 would only send packages while running from IDLE).

This was verified running Wireshark on both machines.

So in short, the 64/64 running from cmd.exe would not send or receive on UDP, while running from IDLE this was not the case.
