Hello Doug,
We are not aware of such bug.
In order to work when EventName is MouseLeftButtonDown you should set
AttachOnHandledEvents=true.
This is needed because Button is handling MouseLeftButtonDown and when this property is true we will also mange to handle it.
As for the border it should work if the border have background (when there is no background then mouse events are not fired).
Kind regards,
Hristo
