But when starting the application, it enters a kind of infinite loop.\r\n  \r\nThe application characteristics:\r\n- Windows 7\r\n- Python 2.7.11\r\n- Kivy 1.9.1\r\n- numpy 1.10.4\r\n- Matplotlib 1.3.0\r\n- OpenCV 2.4.12\r\n- imutils\r\n- tinydb 3.1.3\r\n- psutil 4.1\r\n- pyHook 1.5.1\r\n- Pillow 3.1.1\r\n\r\nIt makes use of multiprocessing so I have implemented the relating recipe: freeze_support(). \r\n\r\nI have followed all the hints and tips I could find but nothing provided me the solution (as far as I could understand these - I am newbee type.....).\r\n\r\nAttached you will find a file containing the .spec file, the output of the PyInstaller build and the logging (Debug mode) when executing the application:\r\n[PyInt-Logging03042016.txt](https://github.com/pyinstaller/pyinstaller/files/201513/PyInt-Logging03042016.txt)\r\n\r\nI noticed the following in the warn~.txt file: I created a test version of the application containing only the multiprocessing flow and primary GUI (Kivy) interaction. This application builds and runs without any problems. But the warn~.txt file of both versions contain about exactly the same list of warnings. So I have attached this file as well.\r\n\r\n[warnpapack.txt](https://github.com/pyinstaller/pyinstaller/files/201519/warnpapack.txt)\r\n\r\nPlease could you help me solving my problems?\r\nThanks very much in advance.\r\n\r\n\r\n"}}
