In my program that I have posted below, the user is suppose to click on a circle that is drawn using a specific color. Depending on whether or not the circle is colored yellow or blue, text will display in the same window as "Correct" or "Incorrect". The problem I am having is after the user click on a circle the text will display, but after the first try, the text that is in the window will remain, leading to the unfortuate problem of each subsequent click causing the new text to write over the previously displayed text. If anyone knows how to get the text to "reset" or "clear" that is in the window, so the window will be blank each time the user clicks, I will appreciate it. Thanks
