Actually I never use IE, my family uses AOL all of the time. What happens is suddenly out of the blue AOL will go to largest font. For some stupid reason AOL 9.0 doesn't have anywhere that I can find that allows you to change font size, so I open up Internet Explorer to change it there. When I do this, I notice that IE also has largest font size. When I fix it from the IE menu the fonts are fine in IE but I need to reboot for the effect to take place in AOL. So this happens without IE even open yet still affects IE. I reinstalled AOL and it still does it.

Unfortunately its not the control button. Pushing it and rolling the mouse wheel doesn't do anything in AOL.
