Hi there,

are you sure that you created the region you wanted. If you accidentally create
a region that is very small (by using the wrong mouse buttons), maybe 
all you see is one raster cell blown up to cover the whole display.
You could use g.region -p or some such to find out what region d.zoom
actually did set.
