Are slats shy ?

[conio]

I'm unsure if the graphics match the FM (i.e. seeing or not the slats deployed currently makes any difference).
Anyway, I noticed yesterday that while powering up the 109, the slats started to pop out and in, out and in (no pun intended).
Since they move relative to the air speed, the slats should be out when the plane is in a stopped state on the ground which seems not to be the case.
