When upgrading Toad to a new version, the Formatter Plus options or settings are not moved over to the new version. The FmtPlus.opt file gets replaced with default settings.
Before upgrading Toad for Oracle, make a backup of the FmtPlus.opt file. After the new Toad version has been installed, copy the backup FmtPlus.opt file to the new installation at default location C:\Program Files\Quest Software\Toad for Oracle, and overwrite the new file.
Waiting for fix in the future release of Toad for Oracle
