Hi,

I manage to reliably reproduce it !

1 Open attached project.
2 Double click MainMenu1 to edit
3 Under MenuItem5, delete MenuItem14,13,12,11
   (I use the - button in the menu editor)
4 The last menu item under MenuItem5 is then 'Action3'
5 Add new menu item (I click 'add menu item' below the Action3 item)
6 Click on Action 3
7 Click on the newly added (in step 5) MenuItem11 
--->> BOOM

Never fails.

The delete step 3 is important. Without that, I don't get a crash.
I then tested deleting a single item instead of 4 items as described above,
then I also get a crash. So as soon as a delete is performed - boom...

Michael.
