 On line 37 of the attached html file, the getPreventDefault method is
 present and called (in Firefox)...at that point, you will get the
 following error reported:


 ----

 uncaught exception: [Exception... "Illegal operation on WrappedNative
 prototype object"  nsresult: "0x8057000c
 (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame ::
 http://localhost/openlayers/examples/clickEventsDebug.html :: <TOP_LEVEL>
 :: line 36"  data: no]

 Line 0

 It seems to me that either the getPreventDefault method should not be
 present as a property of the OpenLayers event object, or if it is, it
 should not crash the JavaScript code when it is called.  I encountered
 this because I had been using the jQuery $.event.fix() method in my
 application, and upon the upgrade to 1.5.2 of jQuery, the $.event.fix()
 method started checking for this method.

 The attached file also illustrates a workaround I was able to use, where I
 overrode the getPreventDefault function with a new empty function (though
 I think deleting the property or setting it false would work as well).
