When they click on upload button it does not open the select file dialog. 

Your demo and our other pages with -only- 1 upload button, all work fine. This page is slightly different since it has 2 upload buttons in it.

Some of our users have the same issue on this page on IE 9 as well,  but so far we havent been able to replicate either one. 

Is there a sample\demo with more than 1 upload button I can look at  please?
