Fix the objects in Layout Means it should not be draggable and moved from its place on sheet..Right...?
If so you can do this,
Go to Sheet properties > Security (Tab) > uncheck (Move/Size Sheet Objects)
If this is not what you want , just let me know with little description of your requirement.
hiiii for this to all your sheets to fix the object
right click on sheet peroperties under security tab uncheck allow/move sheet objects and for all sheets check apply to all sheet then ok
you also have to check that in document properties there's under security tab there's must uncheck the admin override secuirty
if not then uncheck it then it works
hope it helps
