Borrowed this term from javascript.
TPanel, on top TEdit, both have event OnMouseWhellUp.
Move mouse ower TEdit, roll MouseWhellUp, both events gets executed. Probably goes down to form.
Is that expected and out curiosity, can it be turned off.

Yes, that is how it works. MouseWheel messages get sent downwards.
If you want to stop that, then in the top control, let's say the TEDIT here, set the HANDLED:= True in the mouse-wheel event.
