I never had problems with my hihglight function in Word 2007. Since I opened a certain document, nothing special just a Word document, my highlight function stopped working.
I can still highlight text, but after one click with my mouse, the marking stops. Where it should normally should stay on, untill you click the button 'stop highlighting'.
I've alreay called the help desk, but they cannot help me unfortunately. Is there anyone else who had the same problem, but was able to fix it?
