Hello Jeremy,
Thank you for contacting Telerik Support.
Could you please elaborate a bit more on the issue. Are there some javascript errors on page? Under which browser the issue occurs? Is your project deployed on a load balanced environment? Does the problem occurs on every upload? Could you test it under IE9 and Firefox/Chrome?
I will be glad to assist you further.
Regards,
Peter Filipov
