JavaScript Intellisene Problem?

Question

I've got an issue with JavaScript intellisense in Visual Web Developer 2008, which I'm starting to believe is "just one of those things", but thought I'd ask here just to check.

I have a file MyOtherFile.js with a function GetRandomNumber() defined like so:

function GetRandomNumber() {
    /// <summary>
    /// Summary description for GetRandomNumber
    /// </summary>

    return Math.random();
}

When I reference this from another file, screen.js (/// <reference path="MyOtherFile.js" />) I get the intellisense as expected with the summary text as above.

If, however, I callwant the function GetRandomNumber from within its own file (MyOtherFile.js) then I don't get the sumamry description when I type it there.

Any thoughts?

Thanks.
