How can I hide the console window when freezing wxPython applications with cxFreeze?

I'm developing a Python application using wxPython and freezing it using cxFreeze. All seems to be going fine apart from this following bit:

When I run the executable created by cxFreeze, a blank console window pops up. I don't want to show it. Is there any way I could hide it?

It doesn't seem to be documented on the cxFreeze site and Googling didn't turn up much apart from some similar sorta problems with Py2Exe.

Thanks.
