Cursor lagging behind

Hi all,

We have a client with XP SP2 boxes and Office2003 Professional with a
minimum of 1GB RAM. When the legal secretaries prepare a letter, as soon as
they get to page 2 they experience that the screen is not keeping up with
their typing. The cursor is lagging behind.

We were thinking that this would have something to do with a scanned
signature block that is inserted on that page but the size is only 20KB and
the total document is only between 80 and 150KB.

Does anybody have some clues as to where we can start troubleshooting this?

Thanks,
