You must be missing the error messages provided when there are syntax problems. Are you redirecting standard error (which makes sense to keep the screen clean)? Next time, you may want to take a look at error messages reported by the program if they are accessible. Why did you not see the error message about a missing colon when trying to run the script? You might want to put the error back in temporarily, to figure out where those error messages are going. -- Edmond On Thu, Jul 8, 2010 at 8:08 AM, Jon Nelson <dotcop@gmail.com> wrote: > That did not work for me.

Thanks! An oversight on my part. There is still and unacceptable latency in the results. Any thoughts on how to speed it up?
