Hi Jo
I've sorted it out now... I think there was some sort of clash going on with system fonts and Suitcase©. It turned out to be affecting most apps, i.e Firefox wasn't displaying text properly, I was getting the dreaded "Suitcase had a conflict trying to activate Helvetica etc...." dialogue box. I've had this before and it wasn't affecting Terragen this way. I must have had some big conflicts going on. Anyways, Suitcase is sorted and so it seems is TG2.
Thanks, Simon.
