Wow thanks stewer! That makes alot of sense. I appreciate the help from both of you immensely. Now I am stumped on a tkinter problem: I have a button that runs a function. The function runs once when the button is depressed. I want the function to loop as long as the button is held down. Is there some way I could capture mouse events or something to do this? I want to use something like; while (mouse1 pressed on myButton): I really do try figure this stuff out on my own before I ask for help, but this has me stumped. Maybe its not possible? Thanks again!
