I am getting an AV error when checking the "Ignore minor differences" option in the File Differences window when doing a single object compare. I do a single object compare between two packages. When the File Differences window appears after the compare, showing the differences, I go in to check the "Ignore minor differences" option. When U click it, I get the AV error.
When you check the option, it actually takes. If you close Toad, re-open it, and then run the compare again, the option will be checked and run Ignoring minor differences.
If you select Utilities | File Differences, you can change the option in this window without any problems. This will carry over to single compare window.
