[GRASSLIST:8368] Re: New GIS Manager version

[Ian MacMillan]

Michael, I have only one raster in the GIS manager when I do this.  If 
I put a grayscale shaded relief map in the first, and an air photo in 
the second, then I get an 'his' display that is later covered by just 
the first map.  I have attached a small jpg that shows what I am 
talking about.  This screen shot shows my 'his' image getting covered 
up by the  shaded relief map (the shaded relief map does not extend all 
the way to the outer bottom right edge).  For some reason it looks like 
I am getting something like

d.his h_map=air_photo i_map=shaded_relief
d.rast shaded_relief -o

rather than just the d.his command when I hit the display button.

I am also using the binaries from Lorenzo (Sept. 17 - source, Sept. 19 
- osx).  That is weird that you can't reproduce this.

-Ian
