Overlay not showing up

[akisha009]

I had an error " _tkinter.TclError: unknown color name "1" ", renamed my file from overlay.py to window.py and there was no error. While I had error, I noticed there was black box popping up on left up corner of my screen! Now when there is no error, there is nothign popping up, and there is no error, tryed to rename my file again to overlay.py, but no error! Also tryed to reinstall library but nothing... Don't know what to do, there is absolutly no page on entire internet where somone can help me with that, cuz this is no so popular python library, so please help!
