geoffo,   Can you go to the following page and test the iframe mode, flash mode?   http://ajaxuploader.com/Demo/fulltest.aspx   I think for some reasons your silverlight remote access is disabled.

Hi,   You should see the there's a new property UploadCursor   And when your button is pointer cursor style, when use Flash/Silverlight mode , you should see the hand cursor.   Regards, Terry

   We are also facing the same problem.                  

by the way ,   I think you are using Flash8,9 ,   Please try Flash10.   If you can control the PCs of your end users,   I suggest you let them all install silverlight and disable the flash mode.   Regards, Terry    

I see that you have tested with .NET 4 and not seen an issue.  I'm still experiencing these issues on .NET 4 RTM with Silverlight 3 or 4 and using ASP.NET MVC 2.

Like I wrote before, bypassing the Silverlight plugin (and thus using Flash instead) results in a JavaScript error in Internet Explorer: ''Microsoft JScript runtime error: Unable to get value of the property 'length': object is null or undefined''.

Test results in IE9 (with latest Silverlight plugin installed):Auto: does NOT workIFrame: works fineFlash: file gets uploaded, but I get a JavaScript error (afterwards?)Silverlight: does NOT work  

hi OG1, I just upgrade safari to 5.02(7533.185), and all works fine on the demo. I tested with silverlight 4.0 and flash 10. Maybe you can try update the plugins and test on http://ajaxuploader.com/demo/fulltest.aspx Regards, ken

I downloaded the latest version (9/12) and now setting UploadType=''iFrame'' forces iFrame all the time - it is not using Flash or Silverlight anymore.Thanks,Alex 

Hi shaunw,   Please try the latest build here http://aspuploader.com/download/aspuploader.zip, it should fix your silverlight problem.   Regards,   Ken
