There is a huge discussion on how to get the plugin to
work in Opera at http://my.opera.com/community/forums/
topic.dml?id=117477&t=1137121830 -- there is even a
hack to make it work but I really think this should be
handled at the developer level for the plugin.
I hope the developers will consider making the plugin
work in opera. Alot of us would really like it.
