I have the same problem as longshotblues, and today's update hasn't fixed it. I have to click to run anything using Flash (or Silverlight in Netflix). The clip will usually play if it's embedded in (for example) the BBC news sites or Facebook, but Youtube is erratic and BBC iPlayer gives an error. Meanwhile in Netflix itself for some reason I'm being taken to what I think is the US version of the site, which then won't play anything because it thinks I'm in the wrong region.

I haven't changed any settings - all of this just started a few days ago. Chrome continues to run everything fine, so it's very specific to Opera.
