I am working on a drawings with nested xrefs and am experiencing major delays when selecting objects using crossing windows. It is as if the computer thinks I am selelecting the xref even though the curser doesn't touch any visible exref entities. Basically, I click to start the window and the curser freezes for 10 to 20 seconds. I am experiencing the same problem with other commands (intermittenly) such as move, line, and offset. The exrefs are on a separate locked layer and have been moved to the back of the drawing. Does anyone have an explanation for this or a solution?
