new figure invoked from a python shell in Emacs for win32 freezes console even after it's closed

[deuscovrigus]

I have reported this bug on the LP:python-mode project but I think it's independent of python-mode. Here's the description

With the following setup

Ipython 0.13
Emacs 24.1
Windows 7 x64
python-mode.el 6.1.0
ipython.el 2927
matplotlib 1.2.0

A newly created figure in the ipython or regular python console in emacs will freeze the figure window. The console is still active and responding to commands but each figure is frozen.
The py-shell-name variable is ipython.bat containing:

[ipython.bat]
@python.exe -i C:\devel\Python\2.7-bin\Scripts\ipython.py --pylab qt %*

If I run ipython.bat from the windows command line there is no abnormal behaviour and the figure window is responsive. . So far it's only occuring within the ipython emacs shell on Windows. I also tried the Tk backend instead of qt with the same result.

I tested this with the same emacs/ipython setup on OS X and it works fine.
It is also, worth mentioning that with ipython 0.10 . and the same emacs setup on Windows the bug does not occur.

I think it's an emacs-eshell related problem along with the changes in the new version of ipython but I can't get a trace for more details. Any suggestions?

You may want to report this in the IPython tracker as well. Not sure where the issue actually lies, but those folks may have additional ideas.

Closing as the linked SO question seems to have a solution which is making sure console is passed to ipython an a cl argument when the interpreter is started.

Well that did it! Which version of ipython came with the console argument? I know it hasn't been there in the past (prior to v 1.00).
