drag source help

Hi all,

I have an NSView->NSTabView->NSMatrix->NSImageCell which will all be
placed in a drawer of my application. I'm trying to make the icons
inside the NSImageCell's a drag source. My drag destation works
because I can drag images into it, but my source doesn't.

I have a view instance in my NIB window and it's custom class is set
to the class "MyView" which I subclassed from NSMatrix and where I
included the informal drag source protocol including the mouseDown:
method. Also, this class contains an outlet for each NSImageCell which
is connected in IB.

My problem is that I can't get the mouseDown: method to get called
when I click on the icon in my palette (a cell in NSMatrix).

Anyone have ideas what might be going on here? Any help much appreciated.
