Enhancements
------------
stPro
        0662:   A User Preference has been added allowing the user to define the default number of Scale lines for a plot.
                The default can be overridden on a per plot basis via the Plot Properties Details Tab.
        0660:   A new feature has been added that highlights a pen by trebling it's line thickness when the mouse is placed 
                over the corresponding pen entry in the Item Details Area.
        0658:   stPro has been verified on Vista.
        0648:   The Auto scaling method is now a User preference allowing the user to pick "Full Range" (the method used
                prior to V4-2) or "Standard Deviation" (the method used in V4-2).  The default is "Full Range".
        0645:   A number of the stPro dialogs are now resizeable.  To resize them click on the hatched area in the bottom 
                right hand corner of the dialog.  The last size for each dialog is remembered across invocations.
 
stOCX
        0067:   Printing Improvements to make better use of page acreage.
        0066:   The Print function has been elevated to the top level of the right-click menu.
 
stManager
        0173:   The Item Properties Dialog has been reworked to include the Last Used field.  This is the timestamp when a 
                Sapphire Client last requested a data value for the given OPC item and provides a mechanism for knowing
                whether items are being actively trended.
        0169:   The SDR Item list dialog is now fully resizeable.
        0168:   The version and file size limits in the Sapphire Collector have been increased to make it easier to store
                audit files covering longer time periods.
 
stExporter
        0016:   The Exporter now provides an option where the item names written to the Export Output file will be based on 
                the item Aliases, and not the genuine OPC item names.  
 
Bug fixes
---------
stPro
        0664:   Addressed a rendering problem with Stacked Strip Charts where the pens could cross into each other plot regions.
        0663:   The "Last Trended Time" field was not being correctly initialised for CSV plots.
        0659:   It is now possible to load CSV files that contain data values in scientific notation.
        0656:   Fixed a problem where the auto sizing calculation for the Y-axis labels could cause data to be refetched, which
                would then cause the axis to resize, which would again cause data to be fetched and so on.  The result was that
                the Y-axis appeared to 'vibrate'.
        0655:   stPro performance could become very sluggish if the File paths defined in the User section of the registry
                for the most recently used file locations referenced a network drive that was not available.
        0652:   stPro would crash if a timeout occurred whilst manually resolving an item from the Tools->Edit Data source 
        0650:   There were extra background blocks displayed when printing in full colour mode.
        0649:   Deleting a complex virtual expression (one that references the same ‘real’ item more than once) could cause 
                stPro to lock up.
        0647:   The item frequency was not set correctly when loading a plot from an SPHCSV file
        0646:   Disabled columns on the Plot Properties mapping tab were not being correctly hidden.  They were visible on the 
                far right of the dialog.
        0611:   The Preview Pane was not properly applying the time offset between the stPro node and the HDA OPC Server host
                node, so it could display a different time period from the main plot region.
 
Sapphire Collector
        0154:   The Collector was not properly managing requests for export definitions containing more than 50 pens.
        0153:   If Collector’s computer name was the maximum length (15 chars), the Collector would appear listed as "Unknown" 
                on the logon browse dialog.
        0151:   Fixed a memory leak when the auditing O-flag was enabled.
 
stManager
        0172:   Increased the timeout logic in the NetAPI for calls that are expected to take a long time, such as Batch 
                operations.
   
stTabularHistory
        0093:    A timing problem existed whereby data after the start of the current hour would not be shown properly.
        0092:    Addressed a problem reconnecting to HDA OPCServers following a long period of inactivity. 
 
stTHOCX
        0012:   Adding a non existent item using the AddItemViaAliasName API call would result in the day averages not clearing 
                properly for the non existent Item, and a blank name in the properties dialog.
        0011:   It was possible for API calls to fail when switching between stOCX and stTHOCX if they are in the same
                container.  The problem was due to windows initiated initialization taking time to complete. 
 
stOCX
        0064:   If FitToView was called immediately after another API call which fetched data, the scales of pens in Auto scale 
                mode were left unchanged.
 
Installshield
        0052:   The Installshield no longer delivers system Dll's locally if they already exist on the target machine.  This
                avoids the Installshield warning that files are in use by unrelated applications when deinstalling the product.
