Images now really small when I add them to RTF notes

A couple of days ago I dragged a few images into an RTF document in DT, and the inserted themselves into the document at a reasonable size… as I expected they would. Today I dragged a few images in, and they displayed only as tiny thumbnails. If I double click on the images in the DT preview pane, the images open up and they are big. But for some reason, starting today, everything I drag into DT RTFs displays really really small. Did something change? Am I an idiot somehow?

The display of images in RTFD documents uses the DPI information. Maybe some of your images have a higher value than others?
