Everything seems to roll along fine, a few tweaks are still needed, but an issue I cannot resolve has come up. It seems that the checklist items are being selected and added twice to the list, once for a mouse button click, and again for a mouse button release. I thought it would be a simple tag or bind somewhere, like the Python Tk buttons, to limit the selection to the mouse button click only, but I cannot find it anywhere in the documentation.
I am just learning also. Many (most) widgets have a 'command' option for responses to (left) mouse clicks. When available, I suggest using that instead of explicit binding. Let tk get the bind right ;-).
There is a tracker issue posted by someone else who had problem with explicit click binding. He succeeded with 'command = xxx' but failed with supposedly equivalent explicit binding of 'xxx'. I do not know if really equivalent or if tk or tkinter have bug.
