Bug Fixes

The following bugs have been fixed:

• Placeholder: If a table object contained a placeholder which could not be replaced by a value from an NC file, the placeholder would not be removed. This has been fixed.
• The RegisterFunction documentation was incorrect. The documentation has been fixed.
• IC-Editor: Sometimes the edit could not save a file on a network drive when the server was running Windows NT 4.0. This has been fixed.
• Akima spline: The function to calculate the akima spline did not compute the last data point correctly. Sometimes the last point was a huge negative number. This bug has been fixed.
• Formula Interpreter: The min(), max() function did not calculate the min, max values element wise. Instead it calculated the min/max value for the complete channel. The counter() Function falied to be calculated. These bugs have been fixed.
• Data Editor: The copy to clipboard function failed when the data contained missing values. This has been fixed.
• Data Editor: For some netCDF files the C_format attribute was not evaluated correctly. This bug has been fixed.
