Hi folks, I have AutoCAD LT 2012 on my work computer and am have major issues with it taking a long time to complete almost any command for two of my files. It is particularly bad when I switch from paper space to model space or vice versa. It is consitently freezing or crashing entirely. They are big files but not huge at 1400 kb and they do have several xrefs and raster images. The raster images are turned off and the file paths on the xrefs have all been checked. I don't have this problem with other files of similar size and complexity. Any thoughts as to why AutoCAD doesn't like my file? Thanks.
