Crash when inserting notes of very short durations (256th or shorter)
Musescore will consistently crash when inserting notes of small values:
1. Create a new score
2. Change note input mode to insert
3. Change note value to 1024th note
4. Click in the first bar to insert a 1024th note
This happens for any note values equal to or smaller than the 256th note.
If measures need to be created with extra notes of these smaller values, first insert a note/rest of a higher value, select it and click on the smaller value you want, and delete the excess notes/rests that you don't want (Ctrl+backspace).
Is this perhaps caused by some limitation for the smallest length of notes allowed in a bar?
Editing the rhythmic values of a bar in the bar properties dialog limits the smallest subdivision to 64th notes.
