Hi Dev65,
I tested you coed, it works for me.
Please set the UploadType='IFrame' and try again, for example:
<CuteWebUI:Uploader runat="server" ID="Uploader1" UploadType="IFrame">
</CuteWebUI:Uploader>
And do you use Flash 10?
For the Flash10 , sometimes we need the users click again , (if the page layout is not compatible with uploader script code)
You can disabled the Flash10 by this way (in the last version)
uploader.SetAdvancedOption(UploaderAdvancedOption.NoFlash10,"true");
So that if you use Flash 10, it would change to the IFrame mode.
Regards,
Ken
