Code not executing in new console and problem plotting figure

[JimHokanson]

I just installed a fresh version of Anaconda with Spyder 2.3.5.2 and Python 3.4.3 64 bits, Qt 4.8.6, PyQt4 (API v2) 4.10.4 on Windows

When I first ran a script it prompted me for console settings which I accidentally accepted right away. I then went into the settings and changed the run settings to "execute in a new dedicated Python console"

This seemed to have no effect.

I then ran my code in the current console and had a breakpoint put in with:

import pdb
pdb.set_trace()

I then called some plot code:

import matplotlib.pyplot as plt
plt.plot(data)
plt.show()

The figure showed up with the typical icon (IPython) but failed to respond ("Windows not responding").

After restarting and playing around with the settings many times I couldn't get the execution to work as desired or for the plot to not hang.

I then reset Spyder settings via the shortcut that was installed. When I started Spyder again, I was again prompted for execution preferences, and this time I selected the new console right away. This time the code executed as desired and when I plotted the figure showed up with a Spyder icon that I've never seen before (but it works). Looking at the settings (preferences -> run) they look incorrect, almost as if they are no longer referencing the settings that are being used internally.

Sorry, it's not possible to show plots in our Python or IPython consoles while debugging. We hope to solve this problem next year when some improvements are made to Jupyter.

For a workaround see #620 (comment).

Closing as a duplicate of issue #620 itself :-)

Oops, I shouldn't have thrown two issues together. What about the execution settings? This seems to not function properly. Let me know if I should open a separate issue.

I rewrote just the preferences portion in #2540
