"Start without debug" only works a single time, then hangs

Environment data

VS Code version: 1.18.1
Python Extension version: 0.8.0
Python Version: 2.7.14 AMD64
OS and version: Windows 7 x64

Actual behavior

When running python scripts (both via "Start without debugging" or "Start with debugging") the currently open script is executed as expected but python never returns. I can see the python running indicator in the status bar and i can not restart the script. I can also not use the stop shortcut or menu entry. The only way to start the script again is to relaunch vscode. Note that the actual python process IS shutting down. If i select a debug config and hit start it actually jumps in. But if i hit stop in the debug toolbar the python entry in the stack view stays "running" and the blue progress indicator line on top of the debug bar keeps running forever.

Also note that i did try various changes to launch.json. Including reducing it to a single config:

        {
            "name": "Python",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "pythonPath": "C:\\Users\\tkaufmann\\Envs\\seiko\\Scripts\\python.exe",
            "program": "${file}",
            "cwd": "${workspaceRoot}",
            "env": {},
            "envFile": "${workspaceRoot}/.env",
            "debugOptions": [
                //"WaitOnAbnormalExit",
                //"WaitOnNormalExit",
                "RedirectOutput"
            ]
        },
    ]
}

Expected behavior

Running a script via "Start without debugging" should just return to normal state afterwards.

Steps to reproduce:

• Simply run a script using the shortcut or the menu entry

Note: Disabling ctags makes the ctags error in the console go away, the behavior stays the same. Also note, that there was hinted this may be caused by running 32bit python with 64bit code, but this is not the case for me. Both 64bit.
