Swfupload suddenly stopped working in IE (with flash 10 and windows 7)

In our backend-application we make extensive use of swfupload. It has always worked perfectly and we're really appreciating the efforts of the swfupload team. Unfortunately, we keep getting more and more complaints from our customers, saying the u开发者_如何学Cploader doesn't work anymore in their browser (Internet Explorer). The 'select files' button appears as an empty square, with a red cross.

I've spent hours trying to fix this, because also on my computer it doesn't work anymore. I'm using Windows 7 + Internet Explorer 8 + Flash 10.2. I've disabled all of my security settings, but no effect. So I thought, it's because of a wrong implementation, but if I go to http://demo.swfupload.org/v220/simpledemo/, I get the same result. Also, the demo's in the latest beta3 package seem to have the same problem.

I hear and see a lot of people complaining about this, but can't seem to find a proper solution or any response from the swfupload team. Is swfupload dead? Should I choose another tool? Any other people with the same problem?

I also placed this question on the swfupload forums, but I'm not really counting on answers over there.. http://groups.google.com/group/swfupload/browse_thread/thread/344a9079330dd805

This is the response I got from one of the swfupload developers, thought I'd share it with other people searching for a solution (there is none):

"We have users with the same problem (on Windows 7, IE 8 32-bit, Flash 10.1 as I recall it) and we have tried many different suggestions found in various forums but without success. Eventually we had to recommend the users to switch to Firefox."

So, to me, it looks like swfupload is a dead end..
