Thanks David,
I have inserted the kludge-- drawID in the info structure and if
!version.os_family EQ 'unix' and !version.release EQ '5.3' then
Widget_Control .... in the resize routine.
I am about 60% finished reading your book so I will try to write a review
for Amazon next week when I have finished my first reading.
Thanks,
Andy
