My friend (even less computer-literate than I) just got her first laptop. It was working fine last night, but this morning she may have hit a wrong key. When online, the page extends beyond the edges of her screen. There's a horizontal scrollbar, but it's of limited use. Also, the search and drop-down menu buttons at the top are completely missing. There's basically nothing showing above page tabs.
Can someone help us return her page to the normal size, please? To reiterate, this is not happening when she's not online, using regular Windows apps.
Many thanks in advance for any help you can provide!
