I looked all through doc and searched online and cannot find an answer to
this question. I need some experienced help.

I have a cell (a whole column) defined as Text. If the text I type in the
cell includes an at sign (@) the text field displays as ##### (railroad
tracks) most of the time. I have verified the format is text (and word wrap
is on) and it doesn't matter if I start the text with an apostrophe or not.
It also appears to be OK in some text cells but not others. What is the deal?

Thanks.
