Are they slow only when you first start the computer? I find that programs
in general are slow to open when I first start up because, even though all
the startup apps appear to have loaded and there is no hourglass, there are
still bits of my firewall and AV loading in the background, and they seem to
hog the resources. Once they've fully loaded, everything is plenty zippy.
If *all* documents are slow to load (even when Word is already open), this
could be an AV problem, too. If you are running Norton AntiVirus and haven't
disable its Office Plug-in, you need to do so.
