my system is fresh & top of the line. Adobe tech support said it was a known issue too... but that was over a year ago & I've just settled for their opinion since I was crashed beyond all functionality when I called them & the font reduction (plus a re-install) fixed it... so maybe they fixed something on their end before you had different results with CS2... beyond that theory I have no clue why they experienced what I experienced, but you didn't. I will be buying CS3 anyway, so I'll wait till then to load a bunch more fonts.
It's too bad there no longer seems to be the quick fix from a few years ago... just deleting the aiprefs file took care of this back then.
