--- Comment #7 from Dale Mosby dale@archcape.com 2008-12-06 20:45:08 --- I requested a bit of the source in the area that generated this problem. Hopefully the author will be able to provide this and also be willing to do so. With that I would expect that someone used to Windows programming could generate a test case. (I work on Linux no Win stuff for a long time so I'm not the person for that.)
I just did another full installation with wine 1.1.8 including running winecfg after removing th .wine directory. With out the empty "winhttp.dll" file under the .wine/.../system32 directory I am able to perform the program installation step but when I attempt to perform the "test connection" step I get the "failed" message. If I then simply touch the file to create an empty file of this name the "test connection" call reports success.
I also filed bug 16382 to report the improperly drawn screen with the "Proxy Settings" text. I have included two screen shots of the text as I see it. I have never observed this to work properly for me. It might be useful to have some data reported by someone that has seen this correctly. I am not a wine developer so can't do much on my own but can capture winedebug information if someone tells me what to do.
