lynx-dev how to use proxy?

[hy]

hello every one.

I am a novice in using lynx. I encountered a problem yesterday.
Here,we access the internet via a proxy(runing MS proxy and need password) on the LAN.
According to the helpfile come with lynx,I set the httpproxy to it.
But when i try to browse the web,lynx always received a message (form proxy)
that <invalid herder:proxy-authenticate:NTLM>,then a blank screen..
Could anybody help me get it through?
I would really appreciate it.
