It happens both under qemu and real hardware although it seems to be easier to reproduce under qemu.

Here is how:

  1. Single-click on a menu, for example "Settings" in the Terminal app.
  2. Move mouse cursor to center of app. Menu disappeares. (should this really


  1. Move mouse cursor back to "Settings" label and click as fast as possible.
  2. Crash.

Seems to be caused by your latest work on BMenus, Axel. Have you still got pending changes there, or can I try to fix the problem ?

Feel free to fix it, Stefano! I don't think that my changes actually caused it, I guess they just make it more likely to happen (I remember having seen this before).
