Summary: NS 4 onclick & DragEvent

Details: Under Netscape 4.x:
Child layers of a draggable layer do not recieve onclick events. 

Cause:
Cancelling an onmousedown event in NS 4.x prevents the onclick event from
firing. DragEvent.js (from the current release) calls
e.cancelBrowserEvent() in the DragEvent.lyrListener.onmousedown function
(line 26).

Fix:
Commenting out e.cancelBrowserEvent() in DragEvent.js resolves the
symptoms, although I am not sure of the possible repercussions of this.

Test case:
  Click the "X" layer. Console does not show onclick event, but does show
onmousedown and onmouseup events.

  Appply the above Fix and try again. the onclick event fires.
