I have 2 raster layer in global mapper. 1 layer in WGS 84 and geographic coordinate system.(ALOSDEM) The second one is in NAD83 UTM Zone.(SASPlanet Image) Both of these layer are overlayed in global mapper because,as we knew global mapper have the function called "On the fly Projection".
But after i manually change Second layer Using Configure options the result is both of these layer is no longer overlayed.
