Edit "start with score" browsing
In nightly build f22515c:
1) Edit > Preferences
2) "Start with score" window shows ":/data/My_First_Score.mscz"
3) Click browse icon to navigate to alternative score
4) Nothing happens!
If I clear the window, or simply delete the file name from the path, the browse icon works.
Not sure if it's a bug or simply my lack of understanding, again :(
