Why does scrolling with the mouse wheel not work on some computers?
In Geogrid products up to and including Viewer Version 3.2, there is no “genuine” mouse wheel support. Whether or not the mouse wheel works is purely coincidental and depends on the mouse driver installed. In Geogrid Viewer Version 6 (e.g. in Top50 Version 5), scrolling with the mouse wheel is included, as is the “hand symbol” for moving the map.
