Hello Herbert,

Thanks you for your clear bug report above, which I was able to reproduce:<blockquote><hr size=0><!-quote-!><font size=1>quote:</font>

1. Open a new file by following the defaults of “Create a New Song”.
2. Place onto the treble staff a chord of two 1/4 notes, g and c. A single note does not show the problem.
3. Change notes to a single chord tremolo.
4. Select both notes. A single note does not show the problem.
5. Depress the delete button.

Composer terminates.<!-/quote-!><hr size=0></blockquote>I confirmed that this was b bug in version 2.4.2. I have now fixed it for the upcoming 2.4.3 release.

Cheers
