Disable "Tip of the Day"

#1
I am trying to turn off the "Tip of the Day" pop-up that appears each time I launch IntelliCAD. From the online manual I found the below instructions, but I can't find the check box being referred to:

"To prevent the Tip of the Day dialog box from being displayed, click the check box for Show Tips On StartUp to clear it."

Can someone tell me where the disable Tip of the Day check box is located? I have version 10 on windows.
Thank you,
Joe
