CurveExpert Professional 1.6.7 is a maintenance update; no new features, but the robustness update in the nonlinear regression algorithm is certainly worth the update.

• CHANGED: robustness fixes in the optimization algorithm.
• RESOLVED: Some remote reports did not complete successfully.  Fixed.
• RESOLVED: in some situations, a cxp file could not be saved if the number of ticks on the graph was too high.
• RESOLVED: spreadsheet formatting preferences (in Edit->Preferences) did not get applied properly.  Fixed.
