Draftsight freezes when opening a dwg file from autocad LT 2012. Has anyone had this problem? I can open documents created in autocad 2004 no problem. If I open a file created in 2004 with 2004 and copy paste the items from the dwg created in 2012 then re save it in 2004 it still wont open in draftsight? Getting frusturated! Any help would be appreciated! Thanks!
