Automa api running with Python 2.7.6 is hanging my Windows Desktop system

My Requirement:

I have a WPF application that generates a GUI binary - which I am suppose to test.

What's happening:

After successfully installing Automa, and integrated it with Python 2.7.6v - I was able to test my application through Automa alone. It works fine: it doesn't crash/hangs my system regardless of what I do.

Now that I am running the Automa api with Python. While I am running the script, sometimes it is able to run successfully. But when I close the idle during the script running or any abnormal operation happens during the script running. It just freezes my system. The CPU Usage is around 1-2% only and I cannot do anything on my system but to restart it.

What should I do ?

My System:

Windows 7 32-bit OS, Intel Core 2 Duo CPU, 3GB RAM, DELL Optiplex 380.
