When I run the Ajax Uploader on IE8 in Windows 7 it works fine.  Able to upload 1GB.

But when I run IE8 in Windows XP I get the error:

Flash : The upload task is interrupted io Error #2038

 I'm able to do under 100MB but anything over it s me this error.

Any idea?

Thanks, 

 NewmanJerry,

Can you make sure you are using the latest build?

This issue should be resolved.

The latest CuteWebUI.AjaxUploader.dll file I have is:

01/31/2013

Is there a new one?

I'll check now.

Something else it does:

When I upload 1 file that is about 600MB it displays the:

Flash : The upload task is interrupted io Error #2038

But it works fine when I add multiple files that added togther are about 1GB. 

Each of those files are less than 500MB.

Any idea?

But it has issues with IE8 Windows XP  OS
