Help with ACAD_PROXY_ENTITY

[shoman24v]

Hey, I am currently working on a drawing in Autocad Map 2004. There is an object that I cannot delete that is an ACAD_PROXY_ENTITY . It is on the same layer that my border is on. The layer name is "D-BORDER-1". When I click the proxy entity to get the properties of it nothing really shows up, just the stuff under the general tab and a pull down box that just says "ACAD_PROXY_ENTITY". I have done searches on the internet and in Autocads help and it doesn't really explain how to remove this object. I am wonding if anyone here has worked with these and can help me out.

Thanks.
