Fixed a bug that incorrectly computes the offset of a clockwise-specified polygon. This can affect the layout of pieces when the cutting thickness is greater than 0.
Fixed a bug which could crash the application when 1D tabular results window is displayed.
Fixed a bug for not storing the width of columns for 1D results grid.
Fixed a erroneous message stating that 1D results have not been saved even if they have been actually saved to disk.
Fixed some utilization percent (by dividing the result by 100).
