Having problem with upload at work

Hi, I am having one problem with the uploadr. When trying to upload a file, the progress bar rapidly progresses to 100% then a box pops up asking me to authenticate to the corporate proxy server and then the browser locks up and crashes. I am using Firefox 2.0.0.11 running on WinXP.
Thank you for your time and I appreciate your response.
Later versions of Flash
Later versions of Flash Player have stopped crashing and burning for me but authentication does not work behind the proxy at my work.
I haven't found a work-around. There is some functionality in the upcoming Flex3 that may possibly (but probably not) provide authentication support. The current version SWFUpload does not work behind an authenticating proxy.
T_T
Any word on this yet? I know it's only been a month, but I was hopin' for a fix in the 2.02 release, sadly I'm not seeing any changes, perhaps I'm missing something.
If it's any consolation, I've had it work on random, sporadic occasions with Internet Explorer. Never reliably, though. And absolutely never in firefox.
Other than at work, easily best multi-uploader ever.
Thanks, and I'm gonna tinker with it a li'l and see if I can't find some sorta workaround, I'll let ya know if I do.
I have this problem at my
I have this problem at my work as well. It seems to be a Flash Player issue and is completely outside the control of any code that I write for SWFUpload. Flash Player 9.0.115.0 improves somewhat, I can now cancel the password dialog without crashing, but if I try the right or wrong password a couple times then the browser crashes.
Usually in IE I am not prompted for a password and the upload works, but if I am prompted for a password I get the same behavior as FireFox.
One hope is in Flex 3 SDK that you will be able to set the authentication information in code. Flex 3 is still in beta so we haven't looked at using it for SWFUpload yet.
I have this same issue for all Flash based upload tools (e.g., Flickr's upload page crashes my browser at work).

As for the shooting to 100% issue...That is just a side-effect of using a fast, local proxy. The Proxy server receives the entire upload, so as far as the browser and SWFUpload is concerned the file has been 100% uploaded. Then the proxy connects to the target webserver and completes the request which may take some time. There is really nothing we can do about it and it is a limitation of using a client side only upload tool. Some anti-virus software causes the same issues.
Tools that periodically query the server for progress updates (using AJAX, iFrames or some other technology) do not suffer from this issue but have their own set of limitations. In most cases this requires additional server side setup that Flash based solutions don't need.
Flex 3 SDK is released now.
Flex 3 SDK is released now. Did you have any chance using the SDK with SWFUpload? Any other news concerning this issue?
Thx
Flex 3
SWFUpload v2.1.0 is built on the Flex 3 SDK. However, all those great new features only apply to the AIR environment and didn't affect the Flash Player.
So, it's still a no go on authenticating proxies.
