Switches and why they moves

hi,

i just encounter an interesting problem.
I have placed a lot of switches, they don't move they have a strict placement, and in combination with menus i hide or show them as needed.
So for some reasons i don't know, some of the switches move to the far left, out of the screen.
I dont change their position at any time, so how this could be?
Tried to untick the capture options, nothing in behaviour changed.
(for now i set all the switches each time i hit a menu button).

Anyone can explain this..., ran into similar problems..?

thanks
