O ye of little faith?

If only one instance of Sigil is running, enumerating all windows will definitely get you the right title. For example, this code that I stole from stack overflow works just fine:

#!/usr/bin/env python
import ctypes

def run(bk):
 
    EnumWindows = ctypes.windll.user32.EnumWindows
    EnumWindowsProc = ctypes.WINFUNCTYPE(ctypes.c_bool, ctypes.POINTER(ctypes.c_int), ctypes.POINTER(ctypes.c_int))
    GetWindowText = ctypes.windll.user32.GetWindowTextW
    GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
    IsWindowVisible = ctypes.windll.user32.IsWindowVisible
     
    titles = []
    def foreach_window(hwnd, lParam):
        if IsWindowVisible(hwnd):
            length = GetWindowTextLength(hwnd)
            buff = ctypes.create_unicode_buffer(length + 1)
            GetWindowText(hwnd, buff, length + 1)
            if buff.value.find('Sigil') > 0:
                titles.append(buff.value)
        return True
    EnumWindows(EnumWindowsProc(foreach_window), 0)
     
    print(titles)    

    return 0

def main():
    print('I reached main when I should not have\n')
    return -1

if __name__ == "__main__":
    sys.exit(main())
