I'm just trying to get going with AutoSync. Sometimes when I select a number of images, press Cntl, and go to click on AutoSync... it doesn't switch to AutoSync. Other times it does. I can't figure out what is causing it to work sometimes and other times not. I also think that during the times that it won't work, I also can't seem to create a stack from the group of images either. Any idea what is causing it?
