Please provide any additional information below.

Current stable version will install but not function at all.

Partial fix.

Installed current Matplotlib and IPython.
Removed the Matplotlib egg directory as Matplotlib had installed it's own 
directory.

Status:
Launching spyder also launches IPython appropriately now and import matplotlib.
Cannot launch IPython in either Console2 or cmd.exe from the pythonxy launcher.
In fact, the only interactive console that launches is python.
IPython launches fine if run from cmd.exe manually.

There was a previous installation of matplotlib 1.0.1 for 64 bit. Python(x, y) 
is a 32bit. It will work perfectly well on 64 bit Windows (I use it myself on a 
daily basis) but you can't mix 64bit binary package with it!.

IPython 0.12 is _not_ supported in Python(x, y).

Which (ipython, matplotlib) packages did you install??
where they Python(x,y) packages?
