print won't work on Mountain Lion (#22.214.171.124)
The print option won't work in Mountain Lion (maybe nothing to do with this), either via: file > print
or using the shortcut print option on the keypad (cmd/p).
Big thanks in advance!
By the way I can print other documents, in other programs, no problems, just Musescore won't respond, making it almost useless (if you can't print your scores).
