Well, it works for me…  hate saying that..   which version of IE?  I routinely test in IE 8 – 10…

the plupload library we use currently does have an issue in IE 10 with the add files button not working but as the uploader shows, there is a drag and drop section that works fine with IE 10…   hopefully the plupload team will be releasing a fix soon – their next version has been in beta forever it seems…

Using IE 10 and even on this site the “add files” button doesn’t open anything for me too pick a file… though dragging and dropping a file works fine…

which is exactly what I said… its an issue in the plupload js library we use… anxiously awaiting an updated version from them though its a major release increment…
