Problems with effects ans resolution

Question

Hello,
I try to make my personal site but I have some problems I can't find
First, I want to make a transition, here's my code :
<code>
<mx:states>
     <mx:State name="AgdParcours">
          <mx:SetProperty target="{BoxParcours}" name="height" value="317"/>
          <mx:SetProperty target="{HParcours}" name="height" value="317"/>
          <mx:SetProperty target="{HRealisations}" name="y" value="168"/>
          <mx:SetProperty target="{BoxRealisations}" name="y" value="168"/>
          <mx:SetProperty target="{VCV}" name="y" value="250"/>
          <mx:SetProperty target="{BoxCV}" name="y" value="250"/>
          <mx:SetProperty target="{VLoisirs}" name="y" value="250"/>
          <mx:SetProperty target="{BoxLoisirs}" name="y" value="250"/>
          <mx:SetProperty target="{linkButtonParcours}" name="label" value="RŽduire"/>
          <mx:SetEventHandler target="{linkButtonParcours}" name="click" handler="currentState=''"/>
     </mx:State>
</mx:states>
<mx:transitions>
     <mx:Transition fromState="*" toState="*">
          <mx:Parallel targets="{[BoxParcours, HParcours, HRealisations, BoxRealisations, VCV, BoxCV, VLoisirs, BoxLoisirs, VUnivers,                               BoxUnivers, VContacts, BoxContacts]}">
               <mx:Move duration="10000"/>
               <mx:Resize duration="10000"/>
          </mx:Parallel>
     </mx:Transition>
</mx:transitions>
</code>                                                                               
Actually, the effect looks good but there's a bug I can't explain... Here's the result  when I click on the button in the Parcours Box in the bottom right :
There's a transition but it looks bad and after the transition it looks like this :
Well the transition looks good here. But do you know why is there this problem apparently from the box
Secondly, as you can see in the second picture, there's a problem of resolution. Here's my code of my Canvas :
<code>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="1000" height="1314">
</code>
And I can put any numbers in Width and height, it's the same result. Do you know why ?
Thank you

Answer 1

What do you mean by auto-layout ?
Well, Indead I use :
<code>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="1000" height="1314"
creationComplete="parcoursData.send()" >
</code>
What I have to put instead of this Canvas ?
