Forever drawing contours

I have an imported elevation shapefile from the USGS. I wrote our slopes, reread them back in, and then said "Draw contours"

The area is 1 deg x 1deg ---
But teh jiob has run over 6-8 hours without completing -- sometimes it does complete !

Any ideas?

    What sample spacing are you using for the operation and what contour interval? If you use the Gridding tab to break the contouring process into smaller pieces does it then work? I don't know of any issues where the contouring can get stuck, but if for some reason the area provided and sample spacing result in a huge amount of work to be done it might take a really long time to complete.

    Thanks,
