Hi to everyone. I use FSX Fsuipc 4,53 SB4 at vista with saitek multi and radio panel with default B737. But I have problem with saitek radio panel and SB4 with online flights. Whenever I turn on SB4 and there is ATC available then my radio panel freezes. I am pretty sure this frozen caused by SB4 beacuse it works fine when I dont have online flight.Is there anyone who can help me pls?ThnxGuntac
