I currently use a dial up 56k connection(actually only manage 50K average) when flying online with VATSIM. Usually I have no issues. But lately when I fly an event or fly in, my system starts to bog down, I get frame rate stutters and more than a few times complete lock up. I run FS9.1 on XP home, AMD 3000+, 1 gig ram, ATI 9800 SE 128 megs. Once i shut down FS and bring her back up, offline I have to issues. Once I get back online with VATSIM, like last night with the DC fly in, I get "req send/recive player" error messages, no response from ATC and massive frame rate issues. Anyone know what could be causingt this?David Keech

Hmmm...I am on a modem too, but I only seem to have a problem when planes are entering or leaving the session. I don't ever get error messages though. I would suggest you turn down the multiplayer range in SB, so that you don't get all those extra planes constantly joining and leaving your MP session ('cause if they're far enough away you ain't gonna see them anyway...)Good Luck,Marc
