Hi - I'm also having this problem but none of the things suggested in this thread have worked. I still can only select one layer and I need to be able to select and edit multiple. I had clicked "make this the only selectable layer" for one of the shapefiles (A) while I worked on it, but now I need to edit two others (B&C) at the same time and I can't get anything other than shapefile A to be selectable. Even when I remove layer A, I still can't select or edit layer B or C. I've tried restarting Arc and my computer. Has anyone else encountered this? Thanks in advance! -Elaine
