Region Checkpoint: Image Comparsion Mask
Hello, i tried to specify the image comparsion mask for a region checkpoint, but no mask appears in preview (as you can see on the screenshot - yes i clicked the plus arrow before!). What i´m doing ...

The image mask starts out including everything in your image. Use the cursor to define an area on the image. If you then click on the '+', you will add that area to mask. '-' will remove it.
If your mask is all white to begin with, adding to the mask won't change anything.
I defined the area and clicked on '+' but there appears no mask preview.
? But there is a mask preview. It is showing in the image that you included. Perhaps a review of the documentation can help:
As you can see on the attached screenshot, there is no "preview" after including the selected area into comparsion. When i´m saving the mask to region files, there is only a blank image.
