Hi guys and girls, I have the following code

<Button Command="{Binding ResetAll}"  Style="{StaticResource GlassButtonBlue}"  Width="65" Height="65" Canvas.Left="347">
                 <Button.Content>
                     <Image Source="/MainHub;component/Images/Update.png" IsHitTestVisible="False"/>
                 </Button.Content>
                 <Button.Triggers>
                     <EventTrigger RoutedEvent="LostMouseCapture">
                         <BeginStoryboard Storyboard="{StaticResource Reverse_ClickTwice}"/>
                     </EventTrigger>
                 </Button.Triggers>
             </Button>

which just moves some buttons around on my screen and hides the current one. However, the command of the current button does not always fire. Sometimes the animation happens, but neither a click event or a command is fired when the button is clicked. Can anyone tell me why this would happen? I've been told it could be because of the order of events that fire but i'm not sure.

Thanks!
