XPLANE 11 BETA 12. MY CARENADO TBM850 HAD BEEN WORKING FINE FOR TWO MONTHS IN XP11. NOW, WHEN THE RIGHTMOST SOFT KEY IS PRESSED ON THE G1000 MFD, ALL THREE DISPLAYS IN THE AIRCRAFT GO BLANK. PRESS AGAIN THEY RETURN, BUT CANNOT USE THE MFD DISPLAY. ONLY PORTIONS OF THE MFD ARE VISIBLE. CANNOT USE FPLAN FUNCTIONS, MAP, ETC IN THE MFD. NO KNOWN CHANGES IN MY SYSTEM. THE TBM STILL WORKS PERFECTLY IN XP10, SO IT MUST BE A PROBLEM WITH XP11.
