I'm using ArcGIS for Desktop 10.2.1. Several times a day when I try to save an .mxd I get the message:
"Unable to save. Make sure you have write access ..."
I do have write access and there is plenty of space where I'm trying to save it. When I try to Save As ... I get the same message. MXD doctor usually helps, but if not I have to recreate the project.
Is this a common problem with a solution?
