On my Windows 7 system, making changes to the IPython configuration file for the Qt console doesn't seem to have any effect. I just use (and changed) the default profile (not explicitly stated in the commandline, but tried and no effect either). The configuration file seems to be present in the proper location:
C:\Users\<user name>\.ipython\profile_default\ipython_qtconsole_config.py
So what was suggested in this post did not work out for me.
I use IPython 0.13.1 on Python 3.2.3. For Qt bindings, I use PySide 1.1.2.
Any suggestion?
