Thanks Mr. G. The new version does clean the extensionless files in the Opera cache if the cache is in the default install location. I have my machines partitioned for programs and data, and like to keep the cache files on the data partition. When I try and add my custom cache folder with "Options, Include,Add Folder" the "OK" button is greyed out unless *.* is in the box at lower left (won't accept * either). Guess I will revert to the default location unless ther is another solution.
