I am working on a large project, and started setting up the maps I needed for the report a few months ago. Now that the report is due, I went in to make final changes to my maps and export them for the report. I originally set the maps up as landscape 11x17. When I open the maps now, they reverted back to 8-1/2x11 portrait. It wouldn't be bad if I could just change it back and my layout would stay the same, but when I change the page size and orientation, I have to fix the layout. I'm using ArcGIS 1-.4 for Desktop and the mxd's are stored on a removable hard drive. Any ideas on what is happening to my mxd's?
