Outlook 2010 and Word 2010 will randomly switch fonts while typing. It can happen mid sentence. It will switch to a Chinese font and start typing characters such as this "¿ ¿". After this happens you can not use backspace to delete the font, windows will "ding" every time backspace is pressed. It used to switch to a different Chinese character font until i uninstalled it. Now it typically switches to Dotum. I have gone through and removed all the language packs. Any ideas?
Edit: I've noticed it happening when the user corrects an error using backspace.
