Another bug has raised its head

Fix one and another little devil rears. Seems that after doing an edit the transpose no longer works – used to – not sure what I did but will endeavour to fix sometime soon – thanks John Mills for spotting it. Wonder what I did to break that !!

UPDATE:
This is only true if you transpose while the EDIT window is still open. If you close the window before you transpose the song then all is ok. So this is an effective workaround (which relieves some of the pressure on me to do a fix 🙂 )
