I am using Adobe Photoshop Elements 6 and cannot get the Editor Photomerge to work. I use Vista. When I select photos from the bin and click Photomerge Group Shots this comes up "Could Not Complete the Command because the source rectangle is empty" along with 2 empty rectangle boxes 1 highlighted frame labeled source and the other labeled final. When I drag a photo from the bin and drop in source box I get error message "Place Frame". I have tried youtube for a solution to no avail. Any help would be appreciated.
