Every once in a while, I hit some key combination that zooms the screen in with bigger font. Trouble is I don't know what key is causing it or how to back out. I would certainly appreciate some help with this. Just discovered that this condition has nothing to do with the keyboard. Its cause by my wireless Logitech mouse and it happens intermittently when I'm trying to scroll up or down a page using the mouse thumbwheel and press down on the wheel at the same time I'm scrolling. When I happens, the only sure way out is to close down IE and then reopen it where it defaults back to the normal screen size.
