We're having the same problem.  When our users upgrade to Silverlight 4, they no longer get the file selection popup.   We were able to reproduce this problem under Firefox 3.6.3. It worked with Silverlight 3, but not version 4.  This happened under both AjaxUploader 3.0 20091119 and the latest 3.0 20100414.   If you ...

I'm not sure if the thread you linked really describes the same issue. It is true that client certificates use a kind of windows authentication. However I don't know if it is the same problem.   Our problems don't really freeze the browsers we tested (IE/FF). Silverligth and Flash just throw errors and the uploader continues the queue until ...

After disabling firebug the upload worked. But I am seeing a jump of about 500MB in the RAM Firefox uses while uploading a 700MB file. This does cause me some concern, because it is likely that our clients may not have that much spare memory on their machines. Also, I'm having to manually set the Uploader.TempDirectory because it is not ...

We are using the AjaxUploader but are receiving Silverlight errors when uploading files. This is happening in IE 9 with version 5.1.10411.0 of Silverlight. It's strange becuase if you try enough times the file will eventually upload.   The error that we see is Silverlight The upload task is interrupted!   Does anyone know what ...

Thanks for the quick response Eric. Unfortunately, this doesn't work. My issue is trying to get these sizes on the client side without using either silverlight or flash. I'm thinking it is not currently possible; only on the server side.   If you have any other suggestions or tips, I'd really appreciate it. Thanks again.

Hi jmoseley,   You can try the example below, it support resume. Note that, the resume function is  based on the silverlight plug-in, so you need to set the upload type to silverlight and the browser must has the silverlight plug-in ...

Hi chispa,   The dialog filter function is based on silverlight and flash plug-in. On your firefox, it will loads the html5 as the default upload mode. The control will check the file extension again at server side, so i think it will not causes the problem.    you can set property  UploadTypePriority to ...

Dear Ata,   1. upload button is disabled for 5 seconds. It can be clicked 5 seconds after the page is loaded. A: When the page is loaded, the uploader need load 100K script. After the script runs,the script will disable the button, and load the Flash or Silverlight. If Flash/Silverlight can't be loaded by an unknown reason, the script will ...

Hi Ken,   Thanks for that. I will let you know whether that helps but it's for a customers system and am waiting for them to get back to me at the moment.   Can I just ask, what is that latest version of the Ajax Uploader and when was it released?   Thanks Dave
