End Google Ads 201810 - BS.net 01 --> I'm still hung up on that selection, for 3 months now. Nothing I try and no code others provide works even remotely.

Now I think I might use a transparent form that changes size according to mouse movement and check if it's client rectangle intersects with controls that can be selected.

But for that I'd need to have the form's mouse events take precedence over all control mouse events.

Normally, when the mouse is over a control, only the control's mouse events are fired and the form's own mouse events aren't touched, or?

I need to fire the form's mouse event at all times and ignore the control's events instead.

What happens if no control on the form (at least in the area that matters, menus are fine) has any event specified, will the form's events fire then or are they still blocked?

Thank you!
