<FONT SIZE="2"><FONT FACE="Monaco, Courier New"><SPAN DEFANGED_STYLE='font-size:10.0px'>Before I make changes to the d.grid panel in the GIS Manager, I wanted to run by you a couple of thoughts I mentioned to Hamish below.<BR>
<BR>
What do you think?<BR>

(I tried to send this to Bob Covill, but it was bounced)<BR>
