Hi,

I have recently had to update Ajax uploader so it works with IE11. It now works fine with IE 11 but I have a problem with IE10.

The uploader sits in it's own update panel and I also have other controls that sit in their own update panels. If I load the page and try to upload a file without touching any other control it works fine. If I however use another control like a button then try to upload it will not work. The select file dialog box comes up and you can select the file fine but it will not do anything further.

I have tried setting the upload type to "HTML5" and "IFRAME" and it makes no difference. All other browsers seem to work fine. If I set IE10 in compatibility mode then it works fine as well. 

Any ideas?
