Version 4.2.2398 (May 20, 2008) 

• Large data numbers were imported in exponential format.
• Creating a raster Surfer base map did not work with locked layers.
• Zooming-in a single selected marker object caused assertion in Data Manager's grid control.
• There were upside down text and misplaced points when opening some Didger 3 PJT files in Didger 4.
• Could not digitize objects after importing data with Append Fields or Replace Fields.
• GeoTIFF files exported from Didger sometimes imported in incorrect locations in other programs (usually shifted in the Y direction).
• Some complex polygons still exported to SHP in Reverse direction.
• Grayscale images imported solid black.
• Z values in 3D DXF files were imported as 0's.
• Full numbers did not load when loading a DAT file into the Coordinate Conversion dialog box for the georeference operation.
• Assign Elevations was available with polygons.
• Progress gauge got stuck when changing the projection.
• DXF files imported into Didger with text stacked on the first character.
• "Subtract" and "Multiply" text was cut off in Coordinate Conversion dialog.
• When import Unprojected Lat/Long data, you could choose other unit types as the Display Units.
• Didger sometimes hung when a polyline or polygon was digitized under Windows Vista.
• Error when TIF file with LZW compression was imported.
• Assign Elevations included polylines on locked layers.
• Not prompted to change projection when loading a TerraServer image into a project that already has a projection.
• Layer Formatter did not use default properties.
• Some DXF files generated an object conversion error during import.
• In some cases, an exception occurred immediately after exporting a GeoTIFF file.
• Added an “Allow to check for program update periodically” checkbox in File | Project Settings.
• Error in LAS export.
• Projected objects were not moved to the other side of the earth as they should be in some projection.
• Undo Image | Extract Image Region command caused the image to disappear.
• Crash when cancelling digitizing a spline with one point only.

Version 4.1.2234 (January 5, 2008) 

• Corrected a problem where text objects were always created on Layer-1 (or the first created layer).
• Corrected a crash that occurred when the user cleared the Temp Directory file path under File | Project Settings.
• Corrected a problem when not checking the “Clip Map Objects During Export” sometimes caused a crash when exporting.
• Corrected formatting problems in the Report layout for some cases.
• Corrected a problem where the Edit | Undo Grid Edits command caused an internal error.
• Added the Oblique Mercator projection, which was missing from some projection settings.
• Corrected a problem where the Create Base Map command using “Exporting individual objects” sometimes created a blank Surfer project file with no map.
• Corrected a problem where images were sometimes imported upside down if they were calibrated with a descending Y axis.
• Corrected a problem where the Longitude (2nd Point) for the Hotine Oblique Mercator projection was not sticky and was not saved to the GSR file.
• Label Properties section was incorrectly available in the Property Inspector for post maps.
• Corrected a georeferencing scaling problem when importing large ECW files.
• Corrected a problem where converting the projection of large data files sometimes caused a crash.
• Corrected a problem where Didger crashed when exporting to an LAS file and “Use X Axis for Depth” was incorrectly checked.
• Header information in GeoTIFFs exported from Didger 4.0 sometimes gave errors in other software.
• Corrected a problem where rotated text objects in DXF files were imported as horizontal.
• Corrected problem with moving rotated text objects.
• Corrected a crash that occurred when importing USGS Seamless GeoTIFF files.
• Corrected a crash if the user attempted to load too many calibration points.
• Corrected a problem when using the Polygon to Polyline command on a 1-point polygon object.
• Corrected problems that occurred when reprojecting a project with a large number of labeled point objects.
• Added new information to the crash report dialog boxes.
• Added information for 30 and 38 records in DXF files for some entities.

Version 4.0.2136 (September 30, 2007)

• Didger 4 released.
