NSSlider and mouse events

Hello,

I need to know when an NSSlider is being controlled by the user. I though the simplest way would be to subclass NSSlider and override the mouseDown and mouseUp methods. Unfortunately, only the mouseDown method is called. Since NSSlider is a descendant of NSResponder, shouldn't it receive the mouseUp notification? I'm also not getting mouseExited and mouseEntered messages.

The docs talk about setting up a modal loop and a periodic event stream to catch the other events. Unfortunately, that prevents the normal slider operation to occur, and interrupts any other NSTimer events my main window is expecting.

There must be a really simple way to accomplish this, but I'm not finding it. Any ideas?

Thanks!
