I waited for RC5 to come out before I upgraded and I've noticed the DefectMap tool doesn't work the way it used to in Version 1.7. I can get all the options to work if I apply the tool one image at a time but not with an image container holding all the images I want to correct - only the first image is processed and RC5 crashes.
In V1.7, I would iconize the image container and drag the DefectMap triangle over the Image Container icon - seemed to work fine (a few of the optional methods crashed but otherwise it worked OK) and this is the process I used with RC5.
I tried the BatchPreprocessing script as well and I still have problems getting it to recognize a master file but that's a different issue...what I'm questioning is the order it performs the processing - shouldn't the defect map be applied to the raw images and not after calibration??
