I have tried to use os.system to run an application inside python on ms-window. However, the applicaion will grap the python and I could not do anything inside python shell unless I quit the application. Are there any way to avoid this? so I can still type command in python shell. Here is the command I used to open the editor:
After this command if I do not quit the gvim, I could not enter command in python shell.
