I have some links on a web page which, when the mouse is moved over them, cause a small box to appear with an explanation of the link. For some unknown reason, these small boxes are now transparent, even though they have a background colour set, and the underlying text shows through making the contents of the box unreadable. The page hasn't been changed in months, and this is a new phenomenon that occurs only in Internet Explorer.
How can I make the background of the small boxes opaque again?
