Hi Rene, Thanks so much for replying on a Sunday. At first I thought it was a compile or LD_LIBRARY_PATH problem, and have check three ways backward and forward. I keep several versions of root on my machine, so it is possible that I've goofed. I'll delete all the objects one more time and triple check all the paths. Personally, I suspect that it's a deep, nasty bug in my code that is just now being tickled. I just wanted to make sure the interface hadn't changed before I starting a major I/O debugging session.
