I've just released version 3.78 of STG FolderPrint Plus – my main product.
This release contains a fix to an AV that was added by a subtle change on of the components I use. Unfortunately, I rarely turn Preview on and only caught it from user bug reports.
A big thanks for all users that sent bug reports! These really help a lot.
I've also added GIF to the preview system, and added an old request – Register with Explorer is now turned on by default when you install the program on Windows 7 and Vista. That means that you can right-click on a folder on Windows Explorer and click on STG FolderPrint to scan that folder.
