When debugging with IDLE with checkbox "Source" enabled, the source window highlights the current line only when the source window is activated. If one of the buttons of the IDLE debug window is pressed ("Step", "Over" or "Out"), the source window is no longer active and the highlighting of the current line disappears. This makes stepwise execution quite boring. This effect seems to be os specific. I found it on Windows XP SP3 and Windows 7 X64 SP1 both with Python 3.2 and Python 3.2. I tried both Python 3.2 and Python 3.3 on Ubuntu 12.4 LTS, and the problem did not show up. So it seems to be a windows-only problem.
