Unwanted fly-out in qtconsole

Qtconsole opens a fly-out showing the docstring as soon as I type in “(” after the name of a function or a method. For example, if I type in “list(” then I see a flyout with a yellow background with the docstring for “list”. I have tried some of the options in the jupyter qtconsole documentation to get rid of the fly-out with no success.

This link shows how the flyout looks and how it comes up. In the photo, spy is sympy, which is imported in .pythonrc.

Any help showing how to get rid of the fly-out would be most appreciated. In case that is relevant, I work on Linux (xubuntu) and occasionally Mac OSX.
