Courtesy cleff stays although it's not needed anymore
I'm using the revision 3507 from MuseScore 0.9.6.3 on Ubuntu 10.10.
What happens is that in some cases, courtesy cleff stays although it's not needed anymore.
Steps to reproduce the bug:
You need at least to staves in F clef.
- Put a new G clef into one staff in the middle.
- Put another G clef in a previous staff. The courtesy clef in the staff below doesn't dissapear.
The problem also seems to happen with other clefs.
