Try the following from the Database Browser in Runtime tab:

1. Use any driver for MS SQL Server 2000. I used the JDBC-ODBC bridge and the 
Merant-Microsoft JDBC driver. Results were the same.

2. Add connection to a local SQL Server 2000 DB (haven't tried remote). I am 
using MSDE (the 2GB database/5 process limited version). If ODBC, obviously you 
need to set up an ODBC connection.

3. Assuming all went well, you will get the database conenction requested. All 
OK so far for me.

4. Create table. Call it Customer. 

5. Add an ID field (say ID). Set it to INT, pk and unique.

6. Add a second field called Description, not unique, VARCHAR 255, no scale, no 
default value, no index and no constraints.

7. Submit - the following error is displayed.

    Unable to format a command
    create table [{object.owner}.]{object.name}
    {
        {columns}
    }
    null

8. Go back to the default value for Description, and enter a space or other 
string.

9. Submit - saves OK but with a default value.

10. This behaviour is repeated for the separate Add Column option (obviously 
subclassed from the same base, or uses same class).

Is this something modifiable in a config file somewhere? This seriously 
degrades the value of an otherwise excellent addition to the tools.
