Vista Tutorial - 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.
