Hi DT2000
Thanks for presenting your complete script. I have replaced the 'place' instruction by 'pack' ones. Don't use 'place' for ordinary GUI applications. Try to enbed widget-groups in Frames. Also try to use classes for GUI-Applications.
Following i placed two scripts. The first one is not engaging the 'win32print'- and 'sqlite3'-module. The second includes these missing modules.
First script:
N.B. Whishing you a lot of fun with Tkinter & Python.
