If you take your layers into a new project you might be able to make it work I suppose I will try this. Actually, I'm working with polyline features that practically sit atop one another. What I've tried is turning off each layer in the table of contents when I select from one layer or the other, but I haven't actually made one or the other unselectable. It's just frustrating because I've used this tool many, many times with no hangups. I'm new to version 10, though, so perhaps there are some bugs. Thanks for the replies!! Scott Harrison Sardis, MS
