5.9e Changes

The convention for treating floating point errors in sensitivity simulation has changed so that NA is stored instead of the last good value. Percentiles and other computations are done on the restricted data set.
DSS Only: The Pre/Post options specified for a simulation are no longer invoked when the model is run from a Venapp or command file or through the DLL. Use SPECIAL>RUNCOMMAND to run such scripts.
DSS Only: When opened from a packaged application with a calling program the Vensim DSS DLL behaves the same as the Vensim Model Reader DLL - always referencing the calling package.

Bug Fixes

The document tool would sometimes return a blank page when documenting multiple selections or a whole view.
When opening Vensim sometimes a ghost window sizer would appear on a sketch or some toolbars would not be visible.
DSS Only: The COLORCIRCLE and COLORRECT controls could cause Vensim to close when the screen was refreshed in Venapp.
Units checking in equations with :EXCEPT: would report spurious errors.
Reform/Clean and View>As Text would fail on models containing spurious metafile or bitmap data.
The truncation of error and warning output was excessively restricting what displayed when optimizing.
The Sensitivity Graph tool would not label the x axis for Time values above 1000.
Pro/DSS Only: Using the AddEq button in the Equation Editor with a subscripted Level would make all rates inflows for the new equation.
Starting a Game with a model using Data variables could cause Vensim to close.
Date Labels would not always appear in the Table tool.
DLL Only: The Stop button on the work in progress window was not responding.
