Using 64bit python for windows downloaded from python.org on 64bit windows 7.

Python Version 3.2.2
Tk version 8.5
IDLE version 3.2.2

When stepping through code the corresponding line in the editor does not highlight with the code steps.  The windows does update the contents, so it appears to be tracking, but just fails to highlight the line.

Double clicking on the line in the debugger will go ahead and highlight it.  My settings are all default, and I've double checked the color schemes in the "highlighting" dialog.
