Page view jumps cursor off the bottom of screen in note entry mode.
Create a score with enough staves to fill the screen plus at least one more.
Position the last staff so it is completely visible (I like to put it in the middle of the scree, but this is not necessary).
Enter a note that requires a ledger line below the staff
Result: screen jump so entered note is not visible
Expected: screen does nothing since the note was being entered in a completely visible staff.
Work around: Use continuous view since it doesn't happen there.
