Question WPF et communication entre runspaces

Bonjour,

Je rencontre un point de blocage sur une interface que je souhaite empêcher de freezer lors de longs traitements.
Pour éviter ce \"freeze\" je lance mon interface et les futurs traitements dans des runspaces différents et j'y accède par le biais d'une hashtable synchronized en utilisant le concept de \"Thread Safe Collection\".

Pour l'instant mon script est le suivant:
[code:1]
$Hash = [hashtable]::«»Synchronized(@{})
$Runspace =[runspacefactory]::CreateRunspace()
$Runspace.ApartmentState = \"STA\"
$Runspace.ThreadOptions = \"ReuseThread\"
$Runspace.Open()
$Runspace.SessionStateProxy.SetVariable(\"Hash\",$Hash)
$psCmd = [PowerShell]::Create().AddScript({
[xml]$xaml = @\"

\"@

$reader=(New-Object System.Xml.XmlNodeReader $xaml)
$Hash.Window=[Windows.Markup.XamlReader]::Load( $reader )
$Hash.TextBox = $Hash.window.FindName(\"TextBox\"«»)
$Hash.Window.ShowDialog() | Out-Null
$Hash.Error = $Error
})
$psCmd.Runspace = $Runspace
$data = $psCmd.BeginInvoke()[/code:1]

L'interface se lance bien dans un runspace, j'arrive à y accéder facilement grâce à mon hashtable $hash.<le_nom_du_controle> (j'ai pour l'instant uniquement définit window et TextBox).

La modification de valeur (background/contenu/etc) fonctionne correctement, par contre quand je veux aller lire simplement du text dans TextBox. Impossible.

[code:1]$Hash.TextBox[/code:1]

TextWrapping :
MinLines :
MaxLines :
Text :
CharacterCasing :
MaxLength :
TextAlignment :
SelectedText :
SelectionLength : 0
SelectionStart : 4
CaretIndex : 4
LineCount : 1

Mais ce qui est bizarre, c'est qu'en selectionnant le contenu de ce controle j'arrive à récupérer la valeur.

Si quelqu'un a une idée.. je suis preneur. Pourquoi quand il est selectionné il apparait bien, et pas quand il est juste du \"text\".

Merci d'avance
