That is from the event manager.

Thanks in advance

probably because of a corrupt startup flight.

get back the original ultralight Friday Harbour flight.

Close fsx first.

then open fsx.cfg file

find: situation= blah blah

line

and change to: situation=

only.

close and save file.

start fsx.

(leave that as startup flight for a while so you can be sure it's fixed.)

having a different startup flight often causes problems. best leave the original and simply open a saved flight if you want by electing from 'saved flights' list each time.

Takes only a second and prevents weird issues.
