Go tools->options choose spelling and then check the appropriate box for spell check. Highlight thing, maybe check and see if there is an update for outlook express, i am not sure what will cause that problem, look through the tools menu. X's again check settings, it might not allow you to open anything it thinks could be a virus so go tools->options choose security and make sure the box that prevents certain attachments from being opened is unchecked. Otherwise just play around until you figure it out or search google for the problem.
