yes, I am saying that this operation is not straightforward in wxGUI,
user need to do several steps

1) set comp region from raster
2) go to settings, enable -a flag\
3) set comp region from vector
4) probably disable -a

Hm, I added to wxGUI new item to "Set computational region from
selected vector(s) align to raster" (r70276). This is enabled only
when user selects vector(s) and one raster map together. If it make
sense to you I will backport to relbr72.
