Multiple soundfont issue

I've noticed that if multiple soundfonts are loaded, sometimes removing a sound font or adding one that isn't even used in the score will cause the current sound settings to change. Might be something to be looked into.
For instance, I just made a score, threw some notes on a grand staff, changed the sound in the mixer to "honky tonk" piano. I then went into the synthesizer and added one or two soundfonts. Playback all of a sudden is different than it was before, even though I didn't remove the previously used soundfont nor did I change the sound in the mixer. I think what happens is that there are conflicting slots of sounds: if one soundfont has a GM bank, and then you load another soundfont with another GM bank, the newly loaded soundfont will take over the previous sound. I don't think the correct behavior should allow this. One has to go hunting for the previously selected sound in the dropdown list of the mixer.
