There was a small issue when using thumbnail preview images on subpages. This is fixed in 1.0.2 with the extension manager auto updater.
All thumbnails must be reassigned inside the iframe bric in order to populate the correct thumbnail image.
In addition I added a bloc (Cookie Monster Buttons.bex file) for the buttons shown above for the control center. Therefore, redownload the whole Cookie Monster.zip file from my.paddle.com (or from link inside the download email). The new bex file is located inside the zip archive.
