Thanks for the reply with the interesting yet troublesome current situation.
If the old will not do what it was doing presently, let us try the following first, that is, deletion of the Adobe Premiere Elements Pref file, and, if that does not work, the whole 13.0 Folder in which the Adobe Premiere Elements Prefs file exists...in your Windows 7 64 bit
Local Disc C
Users
Owner
AppData
Roaming
Adobe
Premiere Elements
13.0
and in the 13.0 Folder is the Adobe Premiere Elements Prefs file that you delete. And, if that does not work, then delete the whole 13.0 Folder in which it exists.
Be sure to be working with Folder Option Show Hidden Files, Folders, and Drives disabled so that you can see the complete path cited.
Please let us know if the above impacted the Auto Smart Tone interaction with your files brought into it.
Another, sort of way out thought, make a copy of one of your files (one from good before but not now, and one from newer batch with just the bad) and rename the copy of each.
Import the newly named files in the feature and observe the results.
We will be watching for your results.
Thanks.
