When running through a stack of DSLR raw images (using MasterBias and MasterDark), I get the following error for each image:
"File Format Implementation: ExtractKeywords () must be reimplemented in descendant class"
This happens just after the Console message "Loading raw image: 100%", it pauses to let me choose to continue, and then finishes the calibration tasks. It doesn't seem to effect anything (I don't think) other than forcing me to acknowledge the error for each image (time consuming for a stack of 30 images!)
