Dragging and dropping tables to the ER Diagram or Query Builder model area hangs the program.
Per Development, the cause of issue is most likely due to the slow performance of returning results from Database views. Views such as SYS.ALL_CONS_COLUMNS may be used to retrieve information in Toad. Use Tools | SQL Trace | To File menu option to capture all View queries performed prior to dragging and dropping tables.
Issue fixed in version 1.1.0. The latest version of Toad Data Point can be downloaded here.
