elements won't display

so none of my connector, or remote load elements will display in my model. They can be seen if and when I edit them but not when I am just displaying the model. I have tried to hide and then show them in the tree display via r.m.b. but that doesn't change anything.  I assume this is probably just some silly setting that I have inadvertently toggled on..please help.
