hi, have you tried click on tools internet option, fonts then
choosing something like
times new roman
language script latin based
plain text font courrier new

also in internet option click advance
choose restore advance options

 

I like the fonts that they were originally installed with. Which font is that?

 

hi, i am not 100% sure but i believe it is times new roman as i have seen this in many browser as default.
I mean if you have ie7 then instruction i posted above should reset your browser to when you first installed it, though will need to backup your favorites as the will be deleted.
