what a coincidence! a very similar thing happened in our office just today, although not to the extent that you have experienced.
a user in our office was actually deleting some dimensioned elements that were being omitted from the project. the dimension line and 'ticks', as you call them, all disappeared along with the elements, however some of the text - not all
of it - stayed on screen. it could not be deleted!
i told the guy to send and receive, but i must admit that i didn't go back to check to see if it had been resloved. i just put it down to another teamwork quirk. i think that i may have to keep my eye on this . . .
