No idea why your popup is loading a second time, but perhaps as a workaround, you could consider checking whether the user has already provided an answer to the popup.
This is done by using the Answer property on the view. In your case, it might be something like this:
if (CauseSmartPanel.View.Answer == WebDialogResult.None)
{
if(CauseSmartPanel.AskExt() == WebDialogResult.OK) {
}
}
