Hi Alfred,

Yes, this is tricky. I looked at the code and this section
has previously been commented out in TImageScrollBox.Create:

{ MB Jun 16, 2000. These don't seem to be necessary. For the moment
they are commented out, to check for possible side effects
Self.OnMouseDown := Self.ImageMouseDown;
Self.OnMouseMove := Self.ImageMouseMove;
Self.OnMouseUp := Self.ImageMouseUp;
}

Currently the image scroll box only traps the mouse events on the image. Try uncommenting these lines and let me know if this works for you.

Best regards,

Michel
