"Run Module" causes the IDLE to freeze when I start "Run Module" by pressing F5 on the keyboard. But clicking "Run Module" via "Run" on the menu bar have no freezing issue.

Mac 10.6.6

Which Python 3.2 installation are you using?  There are two installers for Python 3.2 for Mac OS X downloadable from python.org, 32-bit-only and 64-bit/32-bit. And which version of Tcl/Tk are you using?  Please start IDLE and report the first two lines shown in the "Python Shell" window, for instance:
Python 3.2 (r32:88452, Feb 20 2011, 10:19:59) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

and then show the results of executing the following lines in the IDLE shell:

import _tkinter, subprocess
print(subprocess.getoutput("otool -L " + _tkinter.__file__))
print(subprocess.getoutput("ls -l /Library/Frameworks/Tk.framework/Versions"))

I'm using the Python 3.2 Mac OS X 64-bit/32-bit x86-64/i386 Installer.

Python 3.2 (r32:88452, Feb 20 2011, 11:12:31) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin

It just freezes every time I try to paste the lines u gave me.
But I mange to edit the .py file via TextEdit. 
here's the result:

/bin/sh: otool: command not found
ls: /Library/Frameworks/Tk.framework/Versions: No such file or directory

It appears then that you do not ActiveTcl 8.5 installed which is required because of deficiencies with the current Apple-supplied Tcl/Tk 8.5 in OS X 10.6.  A warning message should have appeared in your PyShell window:
  >>> WARNING: The version of Tcl/Tk (8.5.7) in use may be unstable.
  Visit http://www.python.org/download/mac/tcltk/ for current information.  Please note the information there.  You need to either install ActiveTcl 8.5 (if possible) or you need to revert to the 32-bit-installer which uses Tcl/Tk 8.4.  Either action should solve the problem.

Thanks a lot Ned!
My problem is solved! Awesome!
