Check Opts Prefs...I forget which heading (chords?) it's set relative to the key it's in.

I have had times when I print out a lead sheet and my wife whites out the chord symbol and changes it.

OTH, I had a 20 minute grumble moment with my electronic tuner. I was tuning a double bell euphonium I was to play for a concert and the darn tuner kept showing A# when I knew I wanted a Bflat. The the light bulb went on. Same note. I do have leadsheets with pencil marks on them. Breath marks, expressions, grace notes...I doubt anyone playing seriously always has a totally clean sheet. I end up with big circles around key changes, coloured high lighters over odd accidentals..it's all in the game.

That might make a good tune..It's all in the game...hmm.
