PRB: "SQL Column '<Memvar>' Not Found" and Empty RQBE Window

MORE INFORMATION

Steps to Reproduce Behavior

1. Type x="CA" in the FoxPro command window.
2. USE the SALESMAN database found in the TUTORIAL subdirectory.
3. Create a new query using the RQBE window.
4. Set up the Selection Criteria as follows:

   Field Name: Salesman.state
   Operator: LIKE (the default)
   Example: x

5. Run the query to make sure it works. It should select four records if the SALESMAN database has not been modified since installation.
6. Save and close the query.
7. In the command window, type "RELEASE x" (without the quotation marks).
8. Open or modify the query. The error message "SQL column 'x' not found" will be displayed.
   
   Clicking the error message will clear the message and the query will open with only the table(s) used remaining. The information under Selection Criteria, Selected Fields, Order By, Group By, and Having will be cleared.
9. Don't save the empty query. If you do, the missing information will be permanently lost.
