the selector is always performed because you don’t cancel it when the mouse is

that’s the missing part.
you need to remove the call.

Hi Eric,
Consider using a single-segment NSSegmentedControl. If the NSSegmentedControl
has both an action and a menu, then you will get the behavior you describe.
Furthermore, it will use the system-standard menu delay, plus make the menu
available to accessibility clients.

I am actually not sure how to pause the execution while holding the mouse

It appears there is a delay...the delay I specified in

Might try pausing execution after the mouse down to see what's preventing the
