I've just introduced a Leopard iMac into my network running a mixture of OS X Tiger and 9.2 machines. Ever since, things have been falling over spectacularly. PDF creation on the other machines has slowed to a crawl, machines are crashing all over the place (including the Tiger ones) and, most annoyingly, I'm having font installation problems on the iMac. Why won't it recognise Postscript Type 1 fonts? The Tiger machines can!
