Are you using OpenType fonts?
Sometime OpenType faces make my computers go sssssssssssllllllllllllllllllllllllloooooooooooooooooowwwwwwwww.
I don't know why. They shouldn't do that, should they? Anyway, I've had maybe a similar problem to yours in InDy and Illustrator. Usually, I get mad an quit everything. Then, when I reload the program, thing go a little faster for a while. Sometimes I convert things to outlines that I know won't change to speed up the process.
It's really the "spinning ball of death" part which sounds loony, not the rest of it. Is that death ball thingy anything like the Rover from The Prisoner? Or perhaps it's the Death Star Logo spinning out of control, brought to you by AT&T.
Have you tried winding up the crank on the side? That's fixed similar problems for me in the past... umm, now that I think about it, that was an Edison cylinder player. Never mind.
I'm starting to wonder how long it'll be before we see the first OpenType virus. "Why does every document I print out with this font say '0wN3D bY l33t haXX0r!!1111' at the top?"
