Traits doesn't, but the (unspecified) underlying GUI toolkit might.
.edit_traits() is usually used when the GUI application object is already
started (e.g. to raise a dialog or embed the UI in another widget, etc.) while
.configure_traits() is intended to create and start the GUI application object
using the one dialog as the initial main window, although it will use an
existing application object if it is running. In somewhat more recent versions
of Traits UI, we use guisupport to handle this, so everything should be fairly
uniform and interact well with IPython's use of guisupport. In older versions of
Traits, I'm not sure. If the OP could state the versions he is using as well as
the GUI toolkit(s), that would help. Also, if he's using one of the --gui
options or not.
