Problem 2: Scrollbars appears on my applet. Solution: Do one or more of the following:
a.) Be sure that your applet is smaller than the frame where you will place the applet.
b.) Set the table margin to 0 (see Figure below) in the HTML code. You can edit it using a text editor such as Notepad++.
c.) Be sure that in your iframe code, the width of your iframe is greater than the width of your applet. This is the same with the height. If scrollbar still appears, try to increase iframe width or height.
Problem 3: The text Created with GeoGebra appears at the bottom of my applet. Solution: Using Notepadd++ or any text editor, delete the text containing the Created with GeoGebra at the bottom of the HTML code.
