I have been using Draftsight for several years and just downloaded the most recent version. I'm finding it unusable. I imported some pdf images and they disappeared after I had worked with them for several days. Now the scale seems to have gone nuts and the screen width in model space is now miles wide. The drawing that I was working on in model space has vanished, I suspect it's there but so minuscule I can't fine it.
What's going on? What is the command to show drawing extents full screen? The command for the properties table seems to have found a new hiding place and I can't find it. Any suggestions other than buying a drafting board and a T square?
