I am seeing problems with Excel 2003 when the Text contents of a Cell will
not display in the worksheet.  When I click into the cell to edit it, the
contents show up in the formual bar.  When I publish the sheet as a web page,
the contents display correctly.   I have tried different text colors and
fonts.   I cannot determine why the cell contents "disappear."  If I edit any
text cell, it "disappears."

I have seen this on several different computers; in some cases the problem
corrects itself after a few days.

Any one have any ideas? Is this a bug in Excel?
