Hi,
I recently updated ArcGIS from 10.4 to version 10.6.1.9270
While the tool 'Mosaic to new raster' still works fine, the mosaic tool/button in the image analyst window just doesn't react. I can click it, but nothing happens. I tried it out with all kinds of raster data, as well on a second workstation. All the other tools in the image analyst window seem to work.
Does anyone know what could be causing this?
