This resulted in:

• The idleperiod setting was chopped down to one character, specifically the first character of whatever the value was previously in Idle Period. IE I had "20" stored in prefs, but the UI showed "2"
• Run-time behavior was according to the chopped value. It sent codes every 2 seconds not 20.
• But it did not re-save a "2" back into the prefs, even though I tried to enter the field to edit it.
• You couldn't edit the value in the UI any more.
• The "2" came from the new IdlePeriod field and not from the old AntiIdleTimerPeriod field, because I had "150" in that field.
