You say you draw roads on the map and they don't stay on the map?

I am willing to bet you a donut, the roads are there, they are just being drawn on a sheet that is well below the others (i.e. If you look at you sheets layering, the SHEET for ROADS or whatever you are drawing the roads on is situatued at the very top or quite near the top of the list). Is this the problem you are having?
