This may be a Mac OS question rather than specifically Quark, but I hope someone might know
On my G5 Mac (10.4.11) I have a number of Helvetica Neue fonts in Fontbook. They are all LWFN format. They operate perfectly well in Quark and other programmes
On a colleagues identical G5 Mac which didn't have these fonts, we have tried to put them into Fontbook but it wont accept them (even after doing a re-start etc)
And we put them in the same location which is > username > library > fonts
Any ideas why?
