[JW Lua] A little help getting off the ground

Thanks for the response.  I met with some success before I got this message.
Apparently your response came in before my re-sent message arrived.

Follow the example in the Wiki for "eachentrysaved()".

d

Replace the inner contents of the example loop with "e.Visible = false"

Feel free to ask anything regarding script development! (Development should
become much easier once 0.03 is available.)

That should NOT happen. I'm starting a timer to for buffering print output.
Perhaps that timer isn't cleaned up correctly.

What operating system are you running?

You should be able to include any Lua package directly from the script, for
example using "require". However, I haven't tested it yet and perhaps I need
to set up some environment variables in JW Lua to get it to work well with
user paths. To get JW Lua to work nicely with 3rd party Lua packages is a
priority of mine.
