Hi,Since I live in Australia, where the transition altitude is 10000 ft and not 18000 ft I have set a level of 10000 in the FMC for this to correspond with the norm in Australian airspace. BUT......the value change in the FMC is not obeyed by the sim which means I get these "Altimeter not set correctly.... press B" message windows and the altimeter setting still gets the yellow box at 18000 ft.When the 737 is loaded up cold and dark the sim pops up that silly message "Your engine is not started......"!!!!! ......As if I didn't know!!Any ideas on how to fix these pesky annoyances?Bernie

Go into realism settings and uncheck the "display flying tips" button. Hope that works. :-)
