Thanks for the suggestion, but my experimenting days are long past.  I don't even know where to begin with this.  My biggest problem is that I don't have broadband and most of the tutorials are video.  I saw a great one on the function editor a couple of weeks ago, but it was so slow that the audio was completely unintelligable.  I watched it for over two hours before I had to give up on it.

I loved Vue 6, but after installing the 8.4 update to Vue 8 I guess I'm wasting my time learning anything.  If you can't save a file and reopen it, it doesn't matter what you learn.

Sorry--just venting.  I'm extremely frustrated.
