Hi Nicola,

sorry for my delayed reaction. Just came back to my computer.

As an immediate workaround do `Smalltalk sendMouseWheelEvents: false`.
This should restore the old behavior. This state is saved
with the image.

If you can afford some time, I would like you to do some testing:

1. Clear your Transcript
2. Do `Smalltalk sendMouseWheelEvents: true`
3. Do `Sensor test`.
4. Do some scrolling.
5. *Press x, to exit this test-method*
6. Activate the Transcript's pop-up menu and select
    'Workspace with Contents'
7. Copy the Workspace's contents to an E-Mail
8. Do `Smalltalk sendMouseWheelEvents: false`
9. Repeat steps 3 to 7


Send the E-Mail to the list.
Hopefully this will give us some clues about
the problem.


Best Regards,

Gerald
