...data set caused error messages to scroll off out of sight in the Messages window (problem reported by Peter Dalgaard). o Improved error checking and protection in distributions dialogs. Version 1.4-3 o Fixed a bug in the scroll-bar for the RHS of model formulas (reported by Ulrich Halekoh). o Fixed problem with some legends in plotMeans() (reported by Rich Heiberger). o Updated Spanish translation (courtesy Rcmdr Spanish translation team).
