PhotoPaint X5 and Windows 7 locks jpg files

I have Corel PhotoPaint X5 running on Windows 7 x64. Every time I save a jpg or jpeg file, the file cannot be shared and appears with a padlock on the bottom left hand corner. To be able to share it, I have to go to the properties of every individual photo and add "Everyone" to the permissions in the Security Tab. Other files save OK. Its only jpg/jpeg files that get locked. Anyone have any ideas how to solve this annoying problem?
