KBArticle 169972 says:
In Microsoft Excel 97 for Windows, if you use these
constants when you insert text into a text box or into a
cell, a square character may appear in the text box or
cell. This problem occurs if you use any of the following
constants:
vbBack vbCr vbCrLf vbNewLine vbTab

.......You can remove the square character by manually
editing the cell.

I have found that this behavior is also in Excel 2000 and
XP. The KB article above is a couple years old. Has
anyone found a solution to removing the boxes
programmatically. I've tried everything I can think of.

Thanks
