The PdxEditor Auto Close shut down timer

As a safety precaution preventing table corruptions by e.g. general power losses or improper computer shut down from computer "green" setting, it is recommended setting the PdxEditor to an Auto Close value shorter than the computer's "green" time-out setting, this way always ensuring a proper close down of tables handled by the PdxEditor before any "green" time-out power shut down.
