Hi,   Please try :   <asp:LinkButton ..... style=''display:inline-block''>   when the <a> is inline display style , the offsetHeight is not correct , so the uploader can't put the Flash/Silverlight layer correctly.   Regards, Terry

Thomas,   If you installed the silverlight , this config would not be applied yet.   Please use UploadType=IFrame or UploadType=Flash to test again.   Regards, Terry

Hi,   Please check the UploadType property , set it to IFrame/Flash/Silverlight mode.   Which mode is slow ?? Is it slow , or stopped ?   Regards, Terry  

Hi,   If your browser do not has Flash/Silverlight, the uploader will use <input type=file /> for it, which do not support dialog filter. Regards, Terry  

Which version of IE are you using? It looks like neither flash or silverlight is installed. Uploader is using Iframe mode.   http://ajaxuploader.com/demo/fulltest.aspx

The demo at http://www.ajaxuploader.com/Demo/select-multiple-files-upload.aspx doesn't work for me, regretfully. I will try downgrading Silverlight to version 4 and see if that changes anything.

Which version of silverlight is supported by the ajaxuploader?

Hi MarjaR, What version silverlight/flash plug-in you are using with your ie browser? Some time load the plug-in will take a few seconds. You just need to wait for the plug-in load complete. Regards, Ken 

Hi MarjaR, This issue should cause by your silverlight 5. Please download the latest version here http://ajaxuploader.com/download/Ajax-Uploader.zip and try again. It should work for you. Regards, Ken 

Hi,   I need to determine if the user was using silverlight/flash/iframe when uploading their files.  Is there a way to do this?   Thanks~
