debugging with idle

[Dirk Zabel]

Hi,
I am trying to debug a script using the idle debug control. I want to 
see the current source line which is executed, so I select the "Source" 
checkbox. If I step through the program, the editor window with the 
source is popping up, but the current source line is not marked. Only If 
I activate the source window by clicking on the window top, the marker 
appears. This I have to repeat for every step: click on "step" button, 
click on source window, click on "step" button, click on source window 
... very boring.
The problem occurs with python 3.3 on Windows XP SP3 as well as on 
Windows 7 X64, SP1.
Running python 3.2 on Ubuntu 12.4 LTE the problem does not come up. Here 
the currently executed line stays marked regardless whether the source 
window is active or not.
Any help is welcome.
Regards
   Dirk
