IE9 JSON Data “do you want to open or save this file”

Начато тестирование моих приложений jQuery с IE9. Похоже, здесь у меня могут быть проблемы. I noticed that when I return JSON data back to the Javascript methods I always get this Prompt that says: "Do you want to open or save this file?" and provides me with 3 buttons: Open, Save and Cancel. Of course, my javascript is taking actions based on the values set in the JSON object but since IE9 doesn't pass it over to the script, I cannot execute the follow up action from there on.

Anyone else facing this issue? Here is a snapshot.
