I have a Textured Window with a NSView that has some custom drawing
done in drawRect.

When I click and drag outside the custom NSView
     The window moves
     (That is exactly what is needed)

When I click and drag within the custom NSView
     The window moves
     The custom NSView receives the mouseDragged messages

Since I am overriding mouseDragged (and most other mouse related
messages in NSResponder) I would expect for the custom NSView to
only receive the messages and since I am not calling [super
mouseXXXXX]; the message should not get outside the NSView therefore
the window should not move.

Clearly that is now what happens. The window moves when I click and
drag within the custom view which is something we dont want to happen.

Does anyone understands what is the flow of mouse events and what to
do to get around this?

The solution is to subclass NSControl instead of NSView.

Actually the solution is to override -mouseDownCanMoveWindow to return
whatever is appropriate for your view.
