I am trying to use the Annotation process to place a few labels on an image. I understand the procedure is to set the parameters in the dialog and then left click on the image. At first I had no luck seeing any text or leader on the image. Then a friend suggested setting the font size up to 72 and the color to something more visible, e.g. red. When I did that, I was able to draw a label on the screen. When I left and returned for another session, I found it no longer worked, even after restarting PI and resetting the size and color parameters to the configuration that previously worked and trying a variety of sizes and colors.
