Prior to switching Python/Tk/Tcl versions, I had no issues with the dropdown working properly. Now, on Python 3.9.0 and Tk/Tcl 8.6, whenever I use the calendar dropdown in my GUI, I notice that an extra blank window opens outside of the main window. It doesn't have the normal structure, it is only a blank space, with no window buttons or text or color.
