Hi, Guys.
I've noticed this problem was raised here already in May of last year but after using CCleaner all my fonts change. Was there ever a remedy to this problem? My mac system fonts are mostly question marks and my browser doesn't display numbers or icons. I also find that when this happens my mail app stops working and closes its self down upon opening. This fixes its self after a reset but it happens everytime I use CCleaner.
Cheers, guys.
