Can someone explain the seemingly extraordinary performance improvement in
using apparently its "split second" vs "over a minute"
set the hidden of line 1 to - 1 of field 1 to false
vs.
repeat with i = 1 the number of lines of fld 1
set the hidden of line i of fld 1 to false
end repeat
it doesn't seem like the loop would be the bottleneck here, but rather the
work on the field itself....but obviously, I know nothing about this engine
:D
Thanks,
