If I run one of my functional tests without the debugger, it runs to
completion fine.

If I run the same test with the debugger, then type 'continue', it fails
with this error:

kellyf@sb61g2:~/dev/rl$ ruby -r debug

Do you have a druby server listening there?

I'm still going to bet you haven't started the DRb service. Depending upon what you shove into the session, you may also need to start it on the client side, which Rails doesn't seem to do for you.

You would win that bet.

What's a DRb service? And what's it doing in my ruby/debug/rails functional
test?

I'm going to search around for information on DRb. I assume the debugger is
looking for it for some reason.

Rails has the option of using a DRb server to store session data. The relevant files in Rails give no indication of how to enable this service, though. I suggest checking back with the Rails list.
