I am experiencing slow performance when exporting from the datagird using the Export Dataset feature regardless of the quantity of rows.
1. Close Toad - very important
2. For Windows 7 go to C:\Users\<your_user>\AppData\Roaming\Quest Software\Toad for Oracle\11.X\User Files
(Note: For Windows XP, the equivalent path is C:\Documents and Settings\<your_user>\Application Data\Quest Software\Toad for Oracle\11.5\User Files
3. Rename the ToadActions.dat and ToadActions.log to ToadActions.dat_OLD and ToadActions.log_OLD
4. Launch Toad and try your export again
