I tried your example (replacing the "('first_line..." with
"['first_line...")
As what you wrote is syntactically not correct, I suspect that you
changed something before posting and did not really ues the posted code?
However for me it works fine under Solaris IDL 5.2.
Only I made the experience that if the widgets YSIZE is set to 1 I got
same behaviour as you.
