Disappearing text

Hi all,

I'm wondering if anyone else has come across this problem.

I have a staff member who is using a laptop (Windows XP and Office 2003) and
her text does not always show. She noticed it first on some emails when she
opened them and there is no body text in them. When opening documents she
occasionally gets an error message that tells her that memory is low but our
technician has ensured this is not the case. In some Word documents, certain
text is not showing even though you can double click it and select the word
or it has grammatical error lines underneath. Dot points do not show up even
though they are switched on. I thought it might be that the font and dot
points were set to white text but this was not the case. We also found that
some of the program labels were also not showing on the screen which leads us
to believe the problem goes deeper than just some settings in the Office
programs.

Have any of you seen this problem before and do you know how to fix it?

Please help if you can,
