Hi Daniel,
see Romano's earlier answer .... it works for me.
Thanks for asking the original question .... it has fixed a long standing but in one
of my programs.
My example program now works ....
rebol []
; fix slider when text list is updated
fix-slider: func [faces [object! block!]]
[
foreach lv-list to-block faces
[
; print [length? head lv-list/lines lv-list/lc]
lv-list/sld/data: 0
lv-list/sn: 0 ; this is the Romano's change
lv-list/sld/redrag lv-list/lc / max 1 length? head lv-list/lines
show lv-list
]
]
tl-data: [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20]
view layout
[
tl: text-list data tl-data 100x100
button "Update it"
[
clear tl-data
insert tl-data [1 2 3 4]
fix-slider tl
]
]
Cheers Phil

Thanks Gregg,
It works partially. The bar now covers the whole vertical space available, that
is good, but then I still need to _try_ to drag the slider to update the list
of items. Otherwise the list shows no items, it appears empty.
