Try using another browser instead of the bult-in one. Install Firefox or Chrome and set it as your default browser. Then login to SL and choose "Use my web browser". Make sure the plugins are enabled.

Then when clicking on your controls panel, select "open in my web browser".

If this does help, contact Live Chat. You are premium therefore entitled to it.
