Had this working great on my computer in 5 different browsers, Visual Studio 2008, Windows 7.  But the upload button won't fire on some of our other computers here - one is using IE8, one is using Chrome, and one is using Firefox 3.6.6, which is exactly what I'm using and it works fine for me.

 

Any ideas what can disable the button?

 

THANKS

If you tested in http://aspuploader.com/demo/form-multiplefiles.asp in those several computers which have this issue, can you reproduce this issue?

 

Regards,

Eric
