The suggestion of LushIsTheLanguage has partly solved one problem I was facing for long time. I have embedded python interpreter in one multithreaded C code with GTK. I could run my *.py script (with pyHook imported in it) from the GTK based GUI only for first time. Next time when I used to run it the full code used to crash. Without pyHook imported scripts I could run any number of times from my GUI.
Now after calling hm.UnhookMouse() and hm.UnhookKeyboard() at the end of the python script I can run it more that one time from my GUI. However still it is crashing after four or five times.
In my *.py script I am not using “pythoncom.PumpMessages()”, rather I am using while loop with “pythoncom.PumpWaitingMessages()”, so that I can break it once any key is pressed.
