Release Notes for FreeFlyer 7.1.1

•Addressed an issue where certain Ephemeris sizes could cause the Ephemeris object to have invalid data stored for some vectors

•Fixed an issue where mapping a time-based column to a FreeFlyer v2 or v3 Ephemeris and then using the Put command with that Ephemeris would cause an error

•Corrected an issue where there was no time-checking for the EphemerisVector object's GetTimeSpanValue method

•Fixed a bug where the runtime API would not initialize if the Windows event log lacked a specific boot time event

•Implemented a fix for an issue preventing the reuse of a runtime API engine after cleaning it up when generating output windows

•The runtime API's language reference files had their version updated

•Optimized performance for ViewWindow object output windows

•Improved performance of the computations associated with ThreeDModel objects

•When using ThreeDModel objects, calling the AddGroup method prior to the LoadModel method will no longer throw a runtime error

•For a Star Map Viewpoint, it will now use a Spacecraft from the ViewWindow constructor as the base object where applicable

•Fixed a crash that occurred when using the Star Map Viewpoint with a Sensor object inside of the orbiting CelestialObject

•Fixed a crash that occurred when using the graphics card after closing all Workspaces

•Fixed a crash that occurred when closing a ViewWindow with a GraphicsOverlay in it

•Azimuth and Elevation Sensor masks now correctly filter out duplicate points and will load correctly if they contain duplicate points

•The VisibilitySegment object will now properly use linear fit for its line of sight calculations when the source is a sensor set to use linear fit

•Addressed a number of cases where FreeFlyer was showing unexpected memory growth for repeated runs of a Mission Plan

•Fixed a crash that occurred when clicking the "Stop Script" button on the UserInterface object preview in its object dialog

•The Jacchia-Roberts file will now be shared among Spacecraft instead of reloaded for each Spacecraft, meaning that large Formations of Spacecraft using this drag model will work as expected

•The TimeSpanArray declaration syntax whereby you specify the size of the array inside of square brackets will now syntax check as expected

•Covariance calculations no longer break down when there is a long-duration FiniteBurn present in the orbit determination algorithms

•Corrected a case where bad AVI codecs could cause FreeFlyer to crash when attempting to generate a movie

•Some cases where Array and Matrix properties wouldn't show up in GUI editors have been fixed

•FreeFlyer will now run properly on the System account even without a My Documents folder
