Mysterious 'x' when retrieving records

[Jacque Scott]

I have a very simple query
 
SELECT ProblemReports.* FROM ProbelmReports;
 
If there is no data in the column 'Description' it returns 'x'.  There
is no default value being used and there is no data in the field.  Why
would it return 'x'?  The field type is 'TEXT'.  I have another 'TEXT'
field in the same table and it doesn't do this.
 
Does anyone have any suggestions?
