Just trace mouse-left-down to see what is wrong:

  0: (mouse-left-down #<my-window-pane :my-window> 1 #.(make-position 174 218))
  0: returned 0

In your example event methods have to be defined for the pane class instead 
of the window class.

The CG documentation could be clearer :

In this situation (if you subclass frame-with-single-child - and thus 
bitmap-window that is a subclass of  frame-with-single-child ) , you also 
should define a pane subclass (as you have done) . And the event methods 
should be defined for the pane subclass (not for the window class, as in 
the CG documentation example that uses a frame-window subclass - see the 
'About events in the IDE'  entry).
