Окно формы Powershell не позволяет запускать javascript

Question

У меня проблемы с открытием удаленного URL внутри этой формы Power-Shell. URL отлично работает вне скрипта power-shell. Я могу запустить его на IE Firefox или Chrome без проблем. Тем не менее, внутри формы, он немедленно выдает java -скриптовые ошибки.
