I just have tried, the button is always disabled :(...

For info, we're using VisualStudio 2008 - Framework 3.1 SP1 and IIS7.0

So according to READ_ME.txt, i use the dll and lic files that are under Framework 2.0-Csharp and in my web.config I added the following entry in configuration/system.web/httpModules

 

Note that I have tried to add the entry above in configuration/system.webServer/modules just for test, but the same error occurs ...

 

Note that the button is disabled only when using safari, everything works fine when using IE. What can be the reason for the upload button to be disabled in safari? Is there another test I can do?
