Hi,

we experienced some differences with IE and Firefox with Flash. If I upload a file with IE the upload speed is half as fast as the upload speed with Firefox. I also can reproduce this with your demo for big file uploads.

If we set the AjaxUploader to IFrame, the speed is almost the same.

We dont have Silverlight installed.

The problem with IFrame is, that we want to calculate and show our own progress in the CuteWebUI_AjaxUploader_OnProgress function but this does not work in IE with IFrame mode. Strangely enough in Firefox this is even working if I set the Uploader to IFrame and disable the Flash Addon.

Another thing is that with IE the calculation of the progress takes more time until it shows up after the upload starts and the time between the progress refresh is higher than with Firefox.

Does the IE have problems with handling flash?

We have IE 9 latest version and Flash 11.5

Thank you

Mark
