The "File->Export->Imagary..." dialog in Terrain Builder 1.31.0.6950 nominally has three file path text boxes:
(1) A file path for "Export satellite texture"
(2) A file path for "Export satellite normal map"
(3) A file path for "Export surface mask"
The first two edit boxes are not positioned where they should be (under their respective checkboxes). Instead, they are both at client position (0, 0), with the "Export satellite normal map" on top.
This makes exporting a satellite texture impossible because you can not enter a file name for it. {F23558}
