Problems with Alter Table (no replies)

Hi there,

I'm using Workbench 5.2.36 CE Revision 8542.
OS is Windows 7 Home Premium SP1.

I'm connecting to a remote MySQL server, version 5.0.77.

I can connect fine, I can expand the table view in the object browser, run queries and edit table data. One thing I can not do though is right click a table and choose 'Alter Table...' to, for example, add a new column.

Whenever I do this I get the following error:

"Error Parsing DDL for 'schemaname'.'tablename'. There was an error parsing the DDL retrieved from the DBMS."

I don't think this is a permissions-based problem since I can alter tables to my heart's content using the same login/connection details on another PC running the old Query Browser. Similarly I can alter tables in Workbench by manually creating and executing the relevent script to add columns.

Any idea what's going wrong here?
