We have just released an add-on for Windows explorer that will display your cross stitch designs as a thumbnail instead of the program icon. This is being given away to registered users of the Platinum version of Cross Stitch Professional for Windows.
To obtain the software, just go to the registered users page and you will see the download link in the yellow box. You can find the registered users page from the Help menu of the program by choosing "Free updates" and then "Visit upgrade webpage".
If you haven't alrady registered your Platinum version, it is not too late to do so. Just go to the Help menu, choose "Free Updates" and then "Register".
The software comes with an uninstaller.
