Canvas MouseUp does not fire ?

Targets macOS
1

I want a canvas to act as a button. So I have placed code in MouseDown that shows the ‘clicked’ backdrop :

if Webviewer.CanGoBack = True then Webviewer.GoBack Me.Backdrop = LarrB

in MouseUp, I want to come back to the default backdrop :

Canvas1.Backdrop = Larr beep

I added beep to make sure the event was triggered. Nothing happens. As if MouseUp never occurred ?

I can go back to the default backdrop in MouseExit and it fires. Why not MouseUp ?

For WEB, I do not know. For desktop, you have to enable it in MouseDown:

Put return True there et voil.
