Chances are that the difference is not in Python itself but in the 
versions of Tk that the two Pythons are linked with.  I wouldn't be 
surprised to find that the 3.1 version is linked with Tk 8.4 and 3.3 is 
with Tk 8.5.  One way to check is:

$ otool -L $(python3.3 -c 'import _tkinter;print(_tkinter.__file__)')
   /Library/Frameworks/Tcl.framework/Versions/8.5/Tcl (compatibility 
version 8.5.0, current version 8.5.15)
   /Library/Frameworks/Tk.framework/Versions/8.5/Tk (compatibility 
version 8.5.0, current version 8.5.15)
   /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 125.2.0)

If you are using the python.org 3.3, please be sure to follow the README 
instructions to install a new version of Tcl/Tk 8.5 (like the ActiveTcl
