    ColorLine tool with a bar series, when you move
    the mouse over the color line the cursor changes
    (to allow drag), but the mouse cursor won't

    several axis set to different positions. It 
    always has the value of defaultaxes position.
7)  TA05010881
    Colorpicker can be opened more than once, If this
    is done the opened colorpicker becomes a kind of 
    ghost window that cannot be selected or closed. 
    Nor can the chart editor and the application be 
    closed. Now fixed.
8)  [No bugfix log]
    Added CustomXRadius and CustomYRadius properties
    for CircledSeries.
9)  TA05013190
    Shadow property is now available for all series
    whose inherit from ICircledSeries.
10) [No bugfix log]
    Setting values for SelectorTool properties gives

    which allows to change this mode and other 
    behaviours.
12) [No bugfix log]
    Added the AsPointLine property to ISeries to
    access to the methods and properties of the
    LinePointSeries.
13) [No bugfix log]
    Exporting a large number of times the Chart to
    PDF (i.e. 5000) in a loop "out of resources"
    error appears. We've been investigating the 
    cause of the problem and trying to find a good 
    solution, however, we'ven't found a fix for it.
    The problem is that when the Chart is exported
    to PDF for a this large number of times, if 
    smooth shadows are used into the Chart, the  
    resources wasted are growing and growing until 
    the error appears. We've tried to control this 
    consumption with no luck.
    So, at the end a workaround for these case when 
    the number of exportations are really big would 
    be to hide the shadows or just set the shadow 
    smooth to false.
14) [TF02012544]
    Zooming or scrolling on a IBubbleSeries
    caused bubbles at the edges of the 
    chart to "disappear". Fixed.

    IBarJoinSeries, IErrorSeries, 
    IErrorBarSeries, IImageBarSeries, 
    IPointSeries, IImagePointSeries
    and IPointFigureSeries. Fixed.

    in size when Marks made visible. Fixed.
