Topic: Bug with new thumbnail selection in Admin Tool

This is an issue with the upload thumbnail action in the admin tool.  Currently, admin tool user can upload a thumbnail to replace the existing default thumbnails. 

The thumbnail upload process generates two files.  One is the original, the other is resized to the thumbnail dimensions.  The bug discovered is that the edit media section will display both files, when the original file is selected, it causes issues with the thumbnail display in the scrolling widget. 

The workaround is to always select the image that is to the left of the list.  The images are displayed based on creation date so the resized thumbnail image will always have a newer date.

We are working to resolve this issue to display only the appropriate thumbnail file.
