I'm using Word 2007, and all of a sudden, CTRL-U no longer works to underline my text. All OTHER font attributes are working fine, and I can still go into the Arial font menu itself, and change the underline to a solid line (which DOES work to underline the highlighted text), but the "underline" attribute on the ribbon menu itself is greyed out. I'm sure I must have done something, but I don't know where to correct it. Thanks in advance for any advice.
