strange symbols appear instead of letters; links download on desktop
1. when typing a ms word document or when typing web addresses while using safari, letters are replaced by weird symbols and characters. it is a sporadic problem - sometimes my computer will be fine for days, and then suddenly while typing the characters return. i've checked my fonts and disabled all of the ones with characters/symbols. the helvetica fractions and times phonetic are NOT in my font book, so i know they are not causing this problem. it is also not a question of hitting F6/num lock. any clues as to what might be generating this problem?
2. sometimes when clicking a link on various RELIABLE websites such as bbc.co.uk the link DOWNLOADS onto my desktop. any ideas why this is happening?
