Scores with big time signatures will be off of the page.
Above is a score with a large number of notes in one measure. This seems to only affect page view, but continuous view seems to be fine.
1. Open MuseScore
2. After going through the starting setup, go to the Master Pallete.
3. Set a big number (minimum not found) on the numerator of the time signature.
4. On the time signature's denominator, set to any note with a bar connecting them (i.e. 1/8 notes, 1/16 notes, etc.).
5. Put in the note on the denominator of the time signature into the measure until the measure is full.
In Page View, it just can't handle it...
