Oops - yes, I did.

Ah, OK, I hadn't copied the connection string before doing the :IPythonClipboard.  That's OK now, I guess (no 'failed' msg anyway).

I'm not sure I'm parsing your comment correctly, but I'm not seeing any "hidden" output in the qtconsole using '_'.  Regardless, see next comment…

I'm not sure what you mean by running "from inside screen".  I simply issue my 'vim' from a Mac "Terminal" (bash) shell.  Nothing shows up in qtconsole when I do this from my vim session (and I also tried doing the '_' in the qtconsole to see if it was somehow hidden.

Maybe I'll get around to trying this on a Windows machine in the next few days just to see if things work for me there.
