I do not observe the problem when launching directly via python interpreter:
python ipython.py qtconsole
or
python ipython.py qtconsole --pylab
I do not see any activity when I leave ipython idle.
window 7 64-bit
python 2.6.6 (32-bit)
PyQt v4.8.3
Perhaps it is from the exe-files that launch qtconsole.
