Does wx-gui work in GRC on Windows

Hi all,
I just installed the latest stable GNURadio and GRC on windows 7. I am
having problems running the fm radio example on GRC. The error shown on
runtime is “Cannot import name wx-gui”. I have PYTHONPATH configured
with
“C:\Program Files (x86)\gnuradio\lib\site-packages” and I have wx-gui
package inside the gnuradio in this path.

Any help to resolve this issue?
Thanks a lot.

Best,
Hemant
