(this is related to the T7 versions)
 
They work totally different than SOs and Quotes.
 
You cannot Display Lines and then select the one you want. No matter what line you click-<enter> or double-click or what button you select (Edit Qtys & Prices, or Edit Line), when you get to the "Edit Line" function you are at the first new line position. Then you have to use the Previous/Next buttons to get to the line you want to edit.
 
It's merely a nuisance when you have one or two lines, but if you have a lot it's a real pain to get back near the beginning.
 
On a related note, while I prefer the functionality of the way SOs and Quotes work, is it an either/or option? In the old days of the non-GUI version we also had the Previous/Next option that is no longer there.
