Along with an earlier query about the instant preview of math; Do you have the 'outline' view open? <it caused some slowdowns a couple of years ago for me, but I thought it got fixed, instead of me just avoiding it.> > > > > Does anyone have any idea of how to fix this problem, or at least how > > to debug it?

This way you might notice some external program being fired up and using a lot of cpu/memory or see the cpu(s) going into IO wait, during the pauses. If you have not used top before, you might want to run and watch top for a few minutes with nothing else going, so you can get used to the rhythm and values of your computer's operation when quiet and thus have a better feel for what is not being quiet when you have issues. Even when this disclaimer is not here: I am not a contracting officer. I do not have authority to make or modify the terms of any contract.
