Defer Panel Updates Property unexpected behavior

Hi all,

Please see the attached VI.  I'm trying to change the colour of some pipe pragmatically.

What I want to happen:

When defer panel updates is TRUE and I change the colour of the pipes, the pipes should only change colour once defer panel updates is set FALSE.

What is actually happening:

When defer panel updates is TRUE and I change the colour of the pipes, the pipes are NOT changing colour once defer panel updates is set FALSE.

LabVIEW help says: If FALSE, LabVIEW immediately redraws the changed elements of the front panel.

So I'm changing the colour of the pipe when defer is TRUE and its not redrawing the changes like it says it should when defer is set FALSE? Any Ideas?

Thanks
