Opera vs Subsonic (Browser update problem)

Opera is in my opinion the best browser to show subsonic in.
But for some months ago I get a problem with the Opera cache it looks like. I do not know what changed. Maybe something in a new version of Opera. Maybe something in a new version of Subsonic.
If I press Play on an album with several songs. Then the songs is added to the playlist as they should. And the VLC player is started as it should.
The problem is if you then start to change the playlist by for instance removing some songs in the list. If you do many such changes you will see entries that you deleted suddenly pop back into the list. But they are not really there. It's just the Opera cache that is misbehaving.
I do not see that problem in Firefox or IE. But those browsers is not showing subsonic as good as the Opera browser.
However I was able to go into the settings in Opera and do changes that fixed this problem. But I feel that it should not have been necessary to do that. Subsonic should had worked with Opera without any need to changes in settings.
Have anyone had the same problem?
If anyone is interested I probably can dig up the changes I did in Opera to make it work correctly with Subsonic.
But I had hoped that Sindre might be able to make a fix of some sort.
