I can recognize exact the same issue with the DC-6. But I have never seen it on any other airplane and it happened the first time after release of 2.0.28. But of course a have installed several other things meanwhile, so there could be some other reason for that issue. What about FSUIPC? I heard many not so cool things about it, also regarding DC-6 issues. Do others here, having the same issue, have FSUIPC installed? I do not start it when running the DC-6 but the issue appears again.
