is buttondownfnc working for anyone?

[Ben Abbott]

On MacOSX, the buttondownfcn isn't working for me.  I'll open a bug report, but 
thought I'd check to see if this is a MacOSX problem is for all OSes.

After the commands below, does a mouse click on the new axes produce any effect?

        graphics_toolkit fltk
        close all
        buttondownfcn = @(obj, event) disp (obj);
        set (gca (), "buttondownfcn", buttondownfcn)
