Yeah, I tried that. Doesn't work whether I double click, or enter 'bitcoin-qt' or 'bash bitcoin-qt' in terminal. It's kind of ridiculous that the feature to run the client easily was removed for 0.9.1 ... I actually went through many other steps from a thread here a while ago, but it didn't help. Sorry, can't recall the thread, and don't have time to 'develop' a fix.

So does anyone know enough about the fine details of the client updates to know whether I'm actually safe to do what I described with 0.8.6?
