Scott, there is no need to set height in the above example
Using just the width i.e t1: txt "Hi" 80 , allows the text to wrap at the
width, very handy if you are laying out a paragraph and don't know how long
it will be the height will autosize.

Scott here is an example for you,
view lay: layout [
t1: text "Hi" black gray
button "Change Text" [
; temporarily set to the max width you wish to allow,
; this allows text to stretch out
t1/size: lay/size
t1/text: "Resize for Scott :-)"
t1/line-list: none
; now set the label size back to the text size
; and add a bit to allow for margins & edge
t1/size: 4x4 + size-text t1
; finally show the result
t1 show t1
]
]
; Should I add this to my FAQ?
