Now that I have narrowed this down to IE, I had to re-ask this question again on the Forum:
Has anyone else experienced similar issue? With Developer tools, I tried to run it in different versions of IE with same result.
It works fine in Chrome or Firefox.
I've saw a similar problem and it was the browser's cache.
After cleaning cache (in this case from IE), everything has worked normally.
Thank you for your response @Damian Culotta. Glad to hear that it worked well for you. It however hasn't worked for me. I've cleared my cachec/cookies/history/downloaded files etc.. from my IE. Anyways, I appreciate your response.
