nohitter151, yes that's the one.

I found out it was spybot blocking the request. Just strange that it makes it crash MM altogether.

Lowlander, now that it works (by disabling spybot), I experience the same behaviour, it opens 2 tabs in Opera. Thanks

For me it opens 2 tabs for each link clicked. This may be the source of your issue. Related bug: http://www.ventismedia.com/mantis/view.php?id=8657

To be clear, do you mean the feature Options > Appearance > Show links in file list?

It works okay for me.

Not much explanation needed here, just clicking on the arrow to search the artist on wikipedia crashes MM completely, Windows telling me MM stopped working.
