Well that's something I have not come accross to date. I tried out what you describe and found that there are aparently to relationships between the end points of the lines at all. The result was, that I could pick the end point but I was not able to seperate them again. I did find it quite amazing to see that two points join together as if they were mated but the property manager shows no relationships at all. So, the question is: What is holding the end points together and why can I not disengage the two again?

It will (I hope) be interesting to hear what others have to say on this one.

Sorry I was not able to help you with your question and instead came up with just more questions but there are some very knowlagable people out there and perhaps we will get lucky and one of them will post the answer for us.

Kind regards,

George.
