Hi all,I have searched the forum to find an answer to this problem but I have been unable to find a topic regarding my particular problem. At any rate, recently I have been receiving a flying tip pop up window while using the 747. It basically says that I have insufficient fuel for the tank selected. Press CTRL X to add more fuel or something to that effect. Even though I go through the process of loading fuel through the PMDG options menu,select apply,etc., and have the correct fuel loaded with no FMC error messages, I still get this pop up window. It's quite annoying. Also, I have flying tips disabled within FS9 settings and still get this message. This has not happened before, so I am at a loss as to why this message appears frequently throughout a flight.I have even gone through the process of exiting a flight and reload the aircraft, but to no avail.Thanks for your input!
