I cannot duplicate that, for the most part.

First, the key signature does matter to BIAB in a number of ways as I mentioned, most notably the enharmonic spelling of notes and chords. I would expect F# to flip to Gb in flatted key signatures like Db, Gb and Ab. But I would NOT expect it to flip in F# or C#.

I'm running build 721 (720 is the latest public release) and I do not have trouble like you are describing. Using the right-hand column (Non-Transpose) I cannot get your results.

So...

Please try something: go to Options, Return to Factory Settings, Most. Save your settings to a file as you do this. Then restart BIAB and try your tests again.
