Mike,

Are the other cells actually losing their values or just seem to go blank
while you are entering the formula?

Sometimes when entering a formula, adjacent cells appear to go blank.

When I start to enter a formula into a cell and I type =, the values
in the preceding 3 columns on the same row disappear.

Anybody have any idea on what might be going on?
