This just started happening to me, and Im not sure why. Every single flash uploader online seems to upload files virtually instantly, and large file (400mb+) upload in a few seconds, but of course the data isn't actually sent that fast, so the uploaders just stall at 100%.

This doesn't just happen on my own sites, but every single site that uses flash uploading.

I reinstalled Flash, and still having same problems.

Any idea?
