My objects are disappearing!

[KLV]

As soon as I draw an object in my chart and click off it, it vanishes. I
know there was someone else with this same problem and it sort of resolved
itself when she re-booted. This has been going on for me for months and I
reboot every day. I go to Format Autoshape and it appears as if White is
selected in the Fill and Line color boxes. I change that to a different
color (e.g. blue) but as soon as I select that color and the color selection
box collapses again, it shows white again. When I click on the drop down
arrow to reselect the color, it shows that the color is already selected
(e.g. blue) but still does not appear for me. The shape remains invisible,
yet knowing where it is, I can click on it.

I'd really like to be able to see my objects! Any ideas?

The box was already unchecked. Any other suggestions?

I'm having the same problem as KLV, plus charts from other people's files
will not display at all. You can see that there is an object there, but it
doesn't have any color.
