I hear ya Ben but i agree with Stéphane, there is a glitch.
Not often, but occasionally Something we do throws the order out but not
visibly in the IDE.

Like i said I have had many a times where 2 objects (eg 2 GridViews) are
expanded in a horizontal panel or a Splitter and for some reason they
become inverted when the program runs. (also buttons in a HBox have got out
of order to what they look in the ide)

They do not switch place in the IDE but when I run the program the 2
objects can suddenly be on the wrong sides.

I usually fix by doing a Cut on the right hand object, then move the left
object a little bit, then paste the right hand object in again.  Then they
usually show correctly again.

I do not know what causes it appear out of order.
