wrong key for new instruments

hello

Windows XP pro
Nightly R 3121

Create a new score with a concert instrument, e.g. flute. Finish with only that one instrument.

Now choose Create - instruments - add a Bb clarinet - OK.

The clarinet does not come with two sharps. Same problem with Eb-instruments.

(if you choose all instruments from the beginning, there is no problem.)
