i'm using IE 6.0 and FireFox 2.0, same behaviour on both browser.
It's this sample that i use.
- I choose 2 files.
- I wait after upload complete.
- After remove a file (postback) and the both file disapairs.
- I upload a file OK (the filename is written near the upload button)
- I click on the postback button and the filename is cleared.
That for this reason, that a have post this message,
After any postback, the control render is reset like when i started your sample.
How is your web.config with your NET 1.1 configuration ?
