I tried that, but it didn't fix it. :(

With a minimal setup, running the R block with a :session makes it ask where the 
working directory should be (the default in the prompt is the directory the test 
Org file is in).  Setting ess-startup-directory to 'default-directory doesn't 
change that, or the output problem.
