Hi ScotFlieger,
thanks for your help - but I did it the hard way: complete deinstallation of FSUIPC and LINDA and a fresh and clean installation thereafter! Laborious and time-consuming, but successful - till now at least. Some minor glitches here and there, but I think I'm on the right way to a functioning cockpit environment.
Best wishes from Franconia, Germany, a merry Christmas and a happy New Year!
