Thanks Tone.

There is a bug. It is in the defineUserProperty routine. Replace the
lines...

    -- If not, then add it a new property.
    if lPropIdx = 0 then
        window_tag[pControl][tagPropId] =
append(window_tag[pControl][tagPropId], pPropId)
        window_tag[pControl][tagPropInit] =
append(window_tag[pControl][tagPropId], pData) -- BUG
        window_tag[pControl][tagPropData] =
append(window_tag[pControl][tagPropId], pData) -- BUG

with...

    -- If not, then add it a new property.
    if lPropIdx = 0 then
        window_tag[pControl][tagPropId] =
append(window_tag[pControl][tagPropId], pPropId)
        window_tag[pControl][tagPropInit] =
append(window_tag[pControl][tagPropInit], pData)
        window_tag[pControl][tagPropData] =
append(window_tag[pControl][tagPropData], pData)

My mistake was caused by copying a line of code twice and only changing one
element reference in each of the two copied lines. This is a common mistake
with using append() etc...
