Thanks for replying Dave.
The instructions you have given exactly describe what I have been doing to display the "Properties|Columns|Constraints|Privileges|SQL" page on which I should be able to create new objects. I can enter details into the properties page and so give my new table a name, but all other pages are read only – especially Columns. Without columns the table is not recorded.
To add a column you click the 'Add' button on the Columns tab...
Could it be that I am not able to see the bottom of this screen? There are no scroll bars – it appears to be interrupted by the program bar at the bottom of the screen.
I suspect an installation problem because pgAdmin’s Elephant icon is suggesting that the application is in a read only mode.
I'm not sure what you mean - the elephant icon is just an icon. It doesn't change to show the application status (and particularly not read-only mode, because there isn't one :-) )
Perhaps you could provide a screenshot of the problem?
Regards Dave.
