How do I really(!!) change the default ringtone?

Question

I have a ringtone on my IPhone 3GS which appears correctly amongst the other tones. When I click upon it, a check mark appears and the sound plays successfully. It is 29 seconds long. But when my phone rings, a different tone (which is marked 'default') is used for the ring instead of the checked one. That different one is marked 'default'. I had thought that clicking upon the ringtine sets it as the default. How can I change the default so that this tone is used instead of the one marked default. Online web instructions say that clicking ought to be enough to select the ringtone used.  When I click upon other tones listed, the 'default' designation does not change to them as well.
Although I do not believe that it is relavant, the following additional information is supplied:  Please note that this ringtone was made by me from a downloaded piece of music. Once before, I had made this into a ringtone, and that time successfuly. But I lost it when I inadvertently reset the phone. Since then, ITunes has changed four times, and this time it would not load the ringtone, even though the ITunes itself had made it. That is why I resorted to an external program. (Yes, I did follow the renaming instructions contained in some of them to verify it ended in 'R'.) An external program, IFunBox was used. It found the file, recognized it as a ringtone, and copied it into the IPhone, where it shows up as a ringtone within Settings.
I believe if I could find a way to make it the 'default', the phone would use it..
Thank you

Jon:
Dragging the thumbnails to the desktop and exporting are essentially the same process, producing copies of the full sized image file. Exporting gives you other options, however. Once you get the photos out of iPhoto you can run PhotoInfo on them and then import as new files. iPhoto will see those new files with the correct date. If you try running PhotoInfo on files already in iPhoto, you can change the EXIF Capture Date in the file but iPhoto won't recognize the changes.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
