problems with i.rectify

[Sam M. Gustman]

     I wrote in before asking for help with i.rectify.  I have successfully
used i.target and i.points.  I get an RMS error smaller then my pixel size.
However, when I perform i.rectify my image gets blown up to enormous 
proportions.  The region I am rectifying to fully contains my image.  Are 
there any other suggestions as to what could be happening?
             Thanks,  Sam Gustman...
