Hello,
I've download your demo and I run it on .Net 1.1 environment
I choose the multiple file (Google like) (http://localhost/Demo/multiple-files-upload.aspx)
I upload 2 files (WORK VERY WELL).
When I wanted to remove 1 file (MAKE A POSTBACK).
And all my other Upload is cleared
I'm interested to your product, but this problem made your product not usable.
Is your product still compatible to .Net 1.1 ?
