[IPython-dev] Session not found: session - seen again on Windows 7, 64-Bit

[Tony Cappellini]

Hello,

I've been seeing problems on a Windows 7, 64-Bit system with the iPython
notebooks.
I'm currently running Python 2.7.10, and iPython 3.2.0

More than once, when I've tried closing a notebook, the notebook did not
close.
Today this issue occurred again, and I've found an error message in the
iP{ython console window.

[I 09:47:00.128 NotebookApp] Kernel started:

n%20Centos%20dev%20system%2C%20using%20yum.ipynb

I tend to use lengthy descriptions in the title field of my notebooks,
based on whatever activities
I was working on at the time I created the notebook. I am wondering if the
lengthy notebook name is causing a problem.I would expect that the file
name length limits be driven by the OS on each particular platform.

I realize the iPython 4.0 was just released, but I tend not to jump on the
bleeding edge, until they have been out there for a while.

Shall I file a bug report?

Thanks

Tony
