Template only works without using proxy

[Daikoku]

I have made a template which should login to hotmail and set some options for the account. The template works fine without using proxies but when using private anonymous proxies the instance crashes.
I tried building the template again and ProjectMaker crashes too when I login to hotmail and switch to Inbox. Anyone has an idea?

EDIT: Solved it! This is an Internet Explorer Bug. Using https:// solved the problem.
