I have a problem which appeared after Draftsight encountered a problem and shut down. After restart I can't set up a sheet for printing, when I zoom to the scale I want the model disappears off the sheet because it is too big to fit on the sheet. It looks like the sheet size display and the model display are at different scales. All was ok before the shutdown.

When I first restarted the sheet view showed the whole of my model and the sheet outline was a tiny dot.

Any ideas how to fix this?
