Hi Andreas,
This turned out to be a bug in Batik's event proxies for JavaScript.
The basic form of the bug is that if you registered for two events on the
same 'listener' the remove would only ever remove the last registered
listener.
The best workaround for this would be to introduce small 'forwarding'
listeners. This is what I tend to do in this case and likely the reason
it
wasn't noticed earlier. For an example of this take a look at my
solitaire
examples. In particular util.js has some 'forwarding' function objects
and the pile.js uses them as members which it registers so that it gets
it's 'mousemove' function called for mouse moves instead of the
generic 'handleEvent'.
This is now fixed in SVN.
