Please find attached, the demo with dummy data. As I mentioned, it was working fine until May 1st. Also, As I mentioned, in case I call MasterApp at the end of add function data appears correctly. This means a malfunction occurred after Windows Update, and it relates to mainloop class MasterApp(object): def __init__(self, root): .... def fun_astinfo_add(self): ... assetinfo_lst.append(lst_values) ... MasterApp(root) ... if __name__ == "__main__": root = Tk() App = MasterApp(root) root.mainloop() ---------- Added file: https://bugs.python.org/file50030/Issue in Tkinter with Python 2.pdf _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44076> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
