jerrycwo4I've been flying the above Constellation along with a number of other programs (weather , audio,etc)and for some unknown reason I can NOT start the engines with Flight Deck Companion running. When I turn FDC off, then the engines will start. Anyone else having this problem. The author of FDC was kind enough to inform me that FDC does not effect this, but in my case, for some reason, it does. jerry

Maybe it's the checklist? Try unselecting one checklist at a time within options and running through startup?
