Thanks for the replys yes it is the addon menu and there it got worse every time I reloaded the. It would get worse in that I couldn't press any buttons I tried stating in a default aircraft but it didn't work. In the end I had to reinstall FSX and everything is resolved. Thanks
Whenever I load up in the 777 747 or 737 at an airport in the U.S. the PMDG systems do not work hence the FMC throttle and other systems do not work however if I load up at an airport outside of the U.S. ie the UK they work a dream. I don't know if this a problem with PMDG or FSX?
Whenever a start a flight within the U.S. the PMDG systems do not load up in the addons column of FSX and so the FMC throttles and other systems do not work however if I load up somewhere outside of the U.S. ie the UK then all the systems are fine and it works a dream. I don't know if this is a PMDG fault or a FSX fault.
