Extracting thumbnails from DNG files
So I tested V1.0.0.1 of CornerFix on Windows 7, and guess what - it broke. Specifically, while images were converted, corrected, etc, they weren't displayed.
A little digging around showed that Microsoft, in their wisdom, have changed the behavior of the .Net 2 Picturebox control. Previously, under both XP and Vista, if the Picturebox control came across a file that it couldn't decode, but could extract a thumbnail from, it would display the thumbnail. Entirely logical and useful behavior, and what CornerFix depended on. That has changed in Windows 7 - all you get now is that Picturebox throws an exception, and displays a little cross icon.
