Recording script with LoadRunner

I'm trying to record a script with LoadRunner but nothing happens...
I'll try to be more specific: I create a new web-based script (Web - HTTP/HTML) because I want to record actions taken into IE.
I start doing things in IE and then stop the recording.
What I expect is to find into "Action" the code that describes what I've just done in IE but nothing appears: "Action"contains only the return.

Any idea about what could be the issue?!
