Floating figures don't work on Windows

[patrick984]

The %%matlab --gui IPython magic does not produce floating figures properly on Windows.

Can be reproduced with the following code (Jupyter Notebook, MATLAB 2014b, Windows 10 x64):

import pymatbridge as pymat
ip = get_ipython()
pymat.load_ipython_extension(ip)

%%matlab --gui
x = linspace(0, 2*pi, 100);
y = sin(x);
plot(x, y)

Figure 1 does appear in the taskbar, however the figure window itself does not appear and clicking on attempting to activate it by clicking on the taskbar entry does nothing.

I was under the impression this was supposed to work as indicated in #150.

Same here, and I'm not using the ipython magic but directly trying to call a matlab function from a python script. The Matlab console works fine, and there is some debug info that shows that the plot was successfully launched, but the plot itself is a freezed blank window.

It's a shame because this library is the most stable python-matlab bridge I have ever found, but this bug prevents me from deploying it.
