Adding line breaks and editing general style stops working
I've had this problem a couple of times now, and I'm not quite sure what to do. After I've been working on a file for a while (in this case, the attached "White Christmas"), some of the formatting functions stop working. For example, I can't add a line break, nor does changing the staff distance (Edit General Style / Page) have any effect. I opened another file (the attached "Sussex Carol") and those operations worked fine, as do other settings (Music upper margin and System distance, for example) for both files. My page fill threshold is set to 100% (and changing it to 70% had the expected effect). I use Mac OS X 10.6.8 and am currently running version 1.3 (revision 5702), but I first encountered this problem in 0.9.6.3 (or possibly 0.9.5 -- I don't remember now). I've already tried reverting to the factory settings and re-installing MuseScore; neither helped. Once this occurs, it seems to be permanent -- I just tried going back to a file I had given up on when I was using 0.9.x (the attached "All My Heart..."), and it still doesn't work in 1.3. (I haven't tried the 2.0 beta, but I can if there aren't any better ideas.) I also tried copying the music and pasting it into a new file, to no avail. Both of the files that don't work were created using the Hymn template that comes with MuseScore, and I did the copy/paste twice -- once into another Hymn template file, and once into a file created from scratch. Unfortunately, I can't tell you the specific series of steps that got me to this point, since I'd been working on the files for some time -- including successfully adjusting the staff distance -- before running into the problem. Does anyone have any suggestions before I go back and start over?
All My Heart This Night Rejoices -- doesn't work
Sussex Carol -- works
White Christmas -- doesn't work
