Try this...
b-one: ["one" "two" "three"]
b-two: ["red" "green" "blue"]
win: layout [
tl: text-list data copy b-one
button "One" [append tl/data copy b-one show tl]
button "Two" [append tl/data copy b-two show tl]
button "Clear" [clear tl/data show tl]
]
view center-face win
Note I added 'copy to the 'text-list definition. If I hadn't the
'b-one block would've been the same block as 't1, and so changed as
well when the buttons were clicked.
