IIS7 AspNet MVC app. Button does not show

[Mark Swiatek]

I have an MVC3 app that works fine on the ASP.NET Development server.
However when I publish it to an IIS site (either on my dev machine or
remote machine), the button to choose the file does not show. In
Firebug, the html looks the same between the development server and
IIS. If I click and drag the mouse, it appears that I can select the
button, but it can't be clicked. If I disable Javascript in my
browser, the button is visible.

The debug output from makeAsyncUploader turns up one important
difference on the development server, the output looks as below.
However on IIS7, there is no SWFDEBUG statements, i.e., it ends after
the SWF Upload Instance Info.

Hi Mark,
I know this is quite old thread, but I have the same problem with a asp.net 3.5 webapp (non-MVC). Did you manage to fix it?

Thanks
