root = Tk()  
name_textBox = Entry(root)
name_textBox.grid(row=0, column=0)
vcmd = root.register(validate_name)
name_textBox.config(validate="focusout", validatecommand=(vcmd,'%P'))
    
    
lname_textBox = Entry(root)

root.mainloop()

Am new to Python and Tkinter i want to trigger validation on an of a app, where entries in a form are adjacent to each other. After input into entry if i move my cursor to another entry my app freezes. How do i fix it I want each entry to validate and for the App to stop freezing. I didnt get any error out of it, it simply just froze. I have no idea why it is happeing. I have have searched and havent seen any answer about here
