I've just upgraded from Autocad 14 to 2005. I am working on drawings that were created on 14. When I'm in paper space and i type MS to modify/zoom/pan within a viewport it automatically does a zoom extents on each and every viewport in Paperspace. I have never seen this on Acad 14 or 2000 before and when i create a new file in 2005 the problem is not there. Your help would be much appreciated.
