Photo Paint X6 Issues after making changes to image

For the last couple months, I've been having issues after making changes to an image in Photo Paint.

I'll change an image, by cropping or rotating an image that is upside down, etc., then save the image to my drive.  But when I access the file using another program (Even just Windows Explorer) or try to post them online, the images don't show the changes I made to them.  However, when I access them using Photo-Paint X6, they reflect the changes.

Does anyone know anything about why this was happening, and what I can do to correct this?
