iTunes-type alternate colored lines in scrolling list field

[Sarah]

Greg,

Download Chipp's altFldHeader stack from 
http://www.altuit.com/webs/altuit2/RunRev/Downloads.htm
This gives you a group of header buttons that allow you to resize the 
columns of a field. You can also specify whether you want the button to 
be active and if so, you can put a sort routine in each one, or set a 
property that specifies the type of sort to do, and have a general sort 
routine that uses this. If you store the settings for the last sort, 
you can do reverse sorts if the same sort button is clicked a second 
time.

Cheers,
Sarah
