Hi Tom, is this a problem with the whole window being the wrong size, or the content in the window has shrunk down and isn't using the full space? Or are things cut off?

To enlarge a window on Windows, you can drag the lower right or upper left corner with the mouse, or use the Maximize button on the top right corner of the window.

Content comes in a variety of widths. Does it help to reset the zoom level? Look for a % number in the address bar to indicate whether the page is zoomed -- that's a reset button to return to 100% (the button disappears when the level is 100%).

In case that doesn't help or I'm not understanding the problem, could you share a screenshot of the problem? Please cut out or blur any sensitive information in the image before attaching it to a reply. This article has tips: How do I create a screenshot of my problem?

Can you attach a screenshot?
