Howdy Herbert,

I'm having difficulty reproducing this problem. Could you please give me the particular steps you're using to see the problem?

My test was as follows:

1. Create a new file.
2. Add a half note on beat one of the first measure.
3. Use the Ornament palette to make that note a tremelo.
4. Select the note, and press Delete.

The note deleted fine for me with no crash. What should I do to see the bug?

Thanks!
Sherry
