PauseStoryboard problem   

Hi All,
    I am experiencing a problem which is turning out to be a bit of a catch 
22.

I am coding a WPF application with VB code behind it. I have an storyboard 
that changes every 10 seconds to display a revolving set of company names.
I added three buttons; one to pause the animation, resume and skip the 
animation to the next set of company names.

This all works but only for the first time the storyboard clock runs for.
After this storyboard ends I re-run the animation using VB code from the 
storyboard_completed event.

This also works fine but after it has been re-run the pause, resume and 
'skip' buttons no longer work with the animation.

I know I could add repeatbehaviour="Forever" to the storyboard and this 
actually solves the problem with the pause and resume buttons not working, 
but then that would break by 'skip' button which uses SkipStoryboardToFill. 
As the storyboard would no longer have an end, this button can not move it to 
the end of the current animation and allow me to display then next set of 
company names.

Here are the key sections of code I am using:
XAML:

        <Border Name="CompaniesBorder">
            <Border.Triggers>
                <EventTrigger RoutedEvent="Border.Loaded">
                    <EventTrigger.Actions>
                        <BeginStoryboard Name="BeginCompaniesAnimation">
                            <Storyboard Name="CompaniesAnimation" 
Duration="0:0:10" Storyboard.TargetProperty="Opacity">
                                <DoubleAnimation Name="DoublePos1" 
Storyboard.TargetName ="Pos1" From="0" To="0.75" BeginTime="0:0:0.00" 
Duration="0:0:0.5"/>
                                <DoubleAnimation Name="DoublePos2" 
Storyboard.TargetName ="Pos2" From="0" To="0.75" BeginTime="0:0:0.10" 
Duration="0:0:0.5" />
                                <DoubleAnimation Name="DoublePos3" 
Storyboard.TargetName ="Pos3" From="0" To="0.75" BeginTime="0:0:0.20" 
Duration="0:0:0.5" />
                            </Storyboard>
                        </BeginStoryboard>
                    </EventTrigger.Actions>
                </EventTrigger>
                <EventTrigger SourceName="btnPause" 
RoutedEvent="Button.Click">
                    <PauseStoryboard 
BeginStoryboardName="BeginCompaniesAnimation" />
                </EventTrigger>
                <EventTrigger SourceName="btnSkip" RoutedEvent="Button.Click">
                    <SkipStoryboardToFill 
BeginStoryboardName="BeginCompaniesAnimation" />
                </EventTrigger>
                <EventTrigger SourceName="btnResume" 
RoutedEvent="Button.Click">
                    <ResumeStoryboard 
BeginStoryboardName="BeginCompaniesAnimation" />
                </EventTrigger>
            </Border.Triggers>

VB.NET:

    Private Sub CompaniesAnimation_Completed(ByVal sender As Object, ByVal e 
As System.EventArgs) Handles CompaniesAnimation.Completed
        CompaniesBorder.BeginStoryboard(CompaniesAnimation)
    End Sub



Thanks in advance for any help.
