WORKAROUND

Please raise a formal case with Quest Support (support.quest.com) and request file 'Toad.exe.config' be sent to you. Refer to this solution (SOL84111)
Once you have received this from Support, close Toad
Rename the 'Toad.exe.config' to 'Toad.exe.config_bak' in your Toad installation folder (C:\Program Files\Quest Software\Toad for SQL Server 5.5 or 5.6) if it exists.
Place the new 'Toad.exe.config' in the Toad installation folder
Launch Toad and retest

STATUS

Waiting for fix in a future release of Toad for SQL Server

Issue also occurs when exporting or printing results from SQL Server Discovery.
