Cannot drag images to container fields
I am using FM Pro 12, and having an issue with dragging images into container fields. And the weird part is that it works sometimes so obviously there is something I am doing that seems innocuous but is not.
I can succesfully drag from Aperture, or from Finder with the expected behavior: the target container gains a blue highlight when the mouse is in the container but still down. When I release the mouse, nothing happens.
I thought perhaps the size of the images (more than 10M and there are hundreds of them) would make a difference but not sure how to compensate for that.
Not much to go on. But I can't think of anything else to try. Any ideas?
