I'm having responder chain headaches. Here's my stack of objects:
RSWindow with custom - sendEvent: to capture and handle with trackingRect for
webView mouse activity.
When the user clicks I create a viewController and add the view as a subview to
the RSWindow.
The viewController provides - deleteLocator: which invokes [[self view]
removeFromSuperview].
A right click on a subview opens a context menu with two options: Edit or
Delete. Delete should remove the subview from the RSWindow.
My issue is with wiring up the menu to the NSResponder chain. When I connect
the Delete menu item to the FirstReponder action in IB the event never fires.
If I connect the Delete button directly to the viewController's deleteLocator:
action outlet the event gets hung up in the RSWindow sendEvent: else { [super
sendEvent:theEvent] } .
Here is a partial of the NSLog dump:

Clearly I am misunderstanding some aspect of the menu-to-Respnder chain setup.
Any thoughts?
It occurs to me I may be trying to remove the viewController from within the
viewController - a lifting-by-the-bootstraps problem ? Should I make the
RSWindow do the removal/deletion ? Or AppDelegate ?
