Hi

This problem sounds similar to one we had quite some time ago. OK so I'm a
home user with one machine but anyway here goes..... We have an iMac 333
with OS 8.6 The cure was installing the following firmware from Apple: 'CD
Update 2.0'. This fixed the glitch. We received the update as a matter of
course from Apple following purchase of our machine in late '99 but I
believe it was also on their website.

This may not be new to you of course but it's the only thing I can think of
if your problem is 8.6 related. 

Coincidentally, installing this piece of fimrware also solved a then hiccup
with our Epson 440 where the print preview appeared as a miniscule blotch
in the preview window and no amount of resetting to deleting fit to page
etc would work. No one I've spoken to could explain this bonus effect but
it was a happy solution.

Hope you solve problem soon
