I'm using version 2011.1.329.35 ,
the RadAsyncUpload is working fine in other browsers (IE,Firefox,etc..),
but it not working in Opera 11.10
strange thing, I' have tested your demo site, that's fine. no any problem.
but in my project, is always show the error tip (red image mark, not green).
am I missing something?
does any one can tell me what I need change?
thanks .
