I have checked option Schema Browser | Data | 'Show filter dialog before refreshing' checked tables not displayed'. I launch Schema Browser and expand table - and the filter dialog will popup
I enter a filter i.e. STARTSWITH 'A'
This returns 'Tables(0)' and no list of tables
To get the actual table list you have to then right click 'Tables' select filter (it's in red now) | OK
The correct filtered list is now displayed
Change to Dropdown view instead Tree view
Issue fixed in version 10. The latest version of Toad for Oracle can be downloaded at:
