Background window grabs focus

Question

Hello there,
I am experiencing a very strange problem in the following situation:
I have a main portal window with a WebDynpro application running.
That application has a TimedTrigger to update its list of products( products are added when submitting a Adobe Interactive Form in a popup, see below ) every 20 seconds.
This application will fire a portal event triggered by a button which is caught by a 'wireframe' view in another component.( with this I mean an empty view, no layout only implementing some methods ) This view is subscribed to the event, fires an actionmethod which is the following:
  public void onActionOpenPopup(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent,
java.lang.String dataObject )
    //@@begin onActionOpenPopup(ServerEvent)
   //TODO more dynamic iView link
    String pcdPath =
      "ROLES://portal_content/<longpath>/iviews/indienenmelding";
    String windowFeatures ="modal=yes,height=700,width=1015,top=0,left=0,status=no,toolbar=no
,menubar=no,location=no";
    WDPortalNavigation.navigateAbsolute(
      pcdPath,
      WDPortalNavigationMode.SHOW_EXTERNAL,
      windowFeatures,
      WDPortalNavigationHistoryMode.NO_HISTORY,
      "bewerken aanvraag",
      dataObject);
    //@@end
The popup displays an Adobe Interactive Form and functions properly.
The problem is the following: whenever a <b>new</b> popup is opened and when the TimedTrigger of the 'parent' WebDynpro fires its action the first time after opening a new popup, the popup looses focus in favor of the parent webdynpro. Just to be exact: when you open multiple popups  each one can cause a focus-loss. When a focus loss has occurred it will not happen again until you open a new popup.
Ofcourse a popup loosing focus is an annoyance for the users so I have to fix this.
My question: what causes this or better: how can I fix this?
For the record: I am not 100% percent sure the TimedTrigger is to blame, just that it takes 20 seconds ( the delay for the trigger ) is a really large pointer.
The code for the action fired by the timed trigger:
  public void onActionRefresh(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionRefresh(ServerEvent)
    try {
      // Automatic refresh is triggered by TimedTrigger UI component
      // refresh this window (if needed)
      boolean upToDate =
        wdThis.wdGetShoppingCartCompController().isScreenUpToDate();
      handleException();
      // Step 2: if not up to date report to the user, else continue submit 
      if (!upToDate) {
        wdContext.currentContextElement().setChecked(false);
        wdContext.currentContextElement().setRefresh(true);
      } else {
        // however, still report a message that shopping cart is empty (if this is
        // the case)
        if (wdContext.currentContextElement().getMode() == null) {
          // as of REL9.1 this means: the regular flavour (not the bupasupport
          // one)
          ShoppingCart cart =
            wdContext.currentContextElement().getShoppingCart();
          if (cart != null && cart.getSize() == 0) {
            wdThis.wdGetShoppingCartCompController().reportMessageEmptyCart();
            handleException();
    } catch (Exception e) {
      handleException(e);
    //@@end
And because it <b><i>may</i></b> be relevant: the code for the wdDoModifyView of the parent webdynpro:
public static void wdDoModifyView(IPrivateShoppingCartView wdThis,
IPrivateShoppingCartView.IContextNode wdContext,
com.sap.tc.webdynpro.progmodel.api.IWDView view,
boolean firstTime)
    //@@begin wdDoModifyView
    // build the shopping cart screen   
    boolean refreshNeeded = wdContext.currentContextElement().getRefresh();
    if (firstTime) {
      // enable submit button
      wdContext.currentContextElement().setRealSubmitTriggerEnabled(false);
      wdContext.currentContextElement().setRefreshTriggerEnabled(true);
      wdContext.currentContextElement().setUserInputEnabled(true);
    if (firstTime || refreshNeeded) {
      wdContext.currentContextElement().setVisibilityNewButton(
        WDVisibility.NONE);
      // try to get the shopping cart from the session
      if (wdThis
        .wdGetShoppingCartCompController()
        .getShoppingCartFromClientState()) {
        if (reportException(wdThis, wdContext, view)) {
          return;
        wdContext.currentContextElement().setTotalVisibleRow(
          wdContext.nodeShoppingCartData().size());
        // enable New button when shopppingcart isn't full yet 
        if (wdContext.nodeShoppingCartData().size()
          < ShoppingCart.MAX_NOTIFICATIONS) {
          wdContext.currentContextElement().setVisibilityNewButton(
            WDVisibility.VISIBLE);
        wdContext.currentContextElement().setReceiptLanguageVisibility(
          WDVisibility.NONE);
        for (int i = 0; i < wdContext.nodeShoppingCartData().size(); i++) {
          IShoppingCartDataElement scd =
            (IShoppingCartDataElement) wdContext
              .nodeShoppingCartData()
              .getElementAt(
              i);
          if ("VBB".equals(scd.getNotificationType())) {
            wdContext.currentContextElement().setReceiptLanguageVisibility(
              WDVisibility.VISIBLE);
            break;
        wdContext.currentContextElement().setRefresh(false);
      } else {
        if (reportException(wdThis, wdContext, view)) {
          return;
Another possible hint: the code worked with NW2004 ( now using NW2004s thus )

Disable the Application Frame in the Window menu.
