Diane and Charles,
Thanks for your replies.
I added NORAT property to main pwrs and gnds.
It Didn't make any difference if schematic and Constraint Manager were 
open or not. (But I have them both closed down)
I have never used Autosilk, but set all params to none.
Still having the same problem.

Thanks,
Mark
