Yes, it's a list field with wrap is disabled. Trying to reduce the font if
the text does not fit. Like this:
Note: device_scaling_factor is calculated on a resize. Here is my code......
repeat with I = 1 to number of lines of field "Results3"
set the textSize of line I of field "Results3" to 60 *
device_scaling_factor
repeat while the width of field "Results3"- the scrollbarwidth
of field "results3" - 5 < FORMATTEDWIDTH of line I of field "Results3"
set the textSize of line I of field "Results3" to the
textSize of line I of field "Results3" - 5
end repeat
end repeat

That depends. is this a list field or regular field? If a regular field, do
you have dontWrap turned on, or not?

Well, you can trap the scrollBarDrag of the field and do something based on
its value, but you'd have to be fast...
