Mike,
I wanted to add just a little more information about this unusual draw order behavior. With regard to my trail map posted above, the last two linear layers are the Nature Trails and the Swamp Rabbit Trail. The Nature Trails are drawing underneath the point layers as they should, but the Swamp Rabbit Trail is the one that is drawing on top of everything. If I move the Nature Trails down in the table of contents, then move the Swamp Rabbit layer back down, then move the Nature Trails down again, and repeat that cycle several times, eventually my Swamp Rabbit Trails are drawn under my point layers. Save map... Close map... Open map. Swamp Rabbit is drawing on top of everything again. It's just strange so I thought I would point it out. Perhaps it might help with troubleshooting and solving the problem.
Thanks again,
Stephanie
