Management Studio strange behaviour

I have a strange problem with Management Studio.

If I attempt to create anything within a database, instead of getting the GUI form to create the item, I am instead given what looks like the raw SQL template.  A re-install of things hasn't made any difference.

For example;  if I right click on the tables node in the object explorer, select New/Table..., I get a pane with SQLQuery1.sql and the contents shown below.  And that is all.

Am I doing something wrong?  Is this an option that I can switch off?

IF OBJECT_ID('<schema_name, sysname, dbo>.<table_name, sysname, sample_table>', 'U') IS NOT NULL
  DROP TABLE <schema_name, sysname, dbo>.<table_name, sysname, sample_table>
GO

CREATE TABLE <schema_name, sysname, dbo>.<table_name, sysname, sample_table>
(
    <columns_in_primary_key, , c1> <column1_datatype, , int> <column1_nullability,, NOT NULL>,
    <column2_name, sysname, c2> <column2_datatype, , char(10)> <column2_nullability,, NULL>,
    <column3_name, sysname, c3> <column3_datatype, , datetime> <column3_nullability,, NULL>,
    CONSTRAINT <contraint_name, sysname, PK_sample_table> PRIMARY KEY (<columns_in_primary_key, , c1>)
)
GO
