fred, yes, i have backups - in fact, the version i am using now is a backup of my version that went corrupt (whole HDD :evil: ) last month. I now have a new install, on a new drive, and was working fine with my maps until the weekend - then suddenly everything went pear-shaped.
literally, from saving my work in the evening - everything fine - to firing up the next day, only to be confronted with this mess.

i'll try my backup copy - (i've tried sys restore - it changed nothing) - hopefully that'll work. still, i like to know why/what happened.
frustrating. :?
