I've been doing some work on the prompts. With these changes you can access those pages that require username/passwords. hopefully it'll work for you

I can also upload a snapsot for those that can't get mozilla to compile, I just need webspace

add #include "Prompt.h" at the top

Can't you get freespace from Freedrive or somekind???

#define IDC_EDITBOX 1003 is already defined in resource.h BTW,
now if sourceforge finally could get my CVS access fixed, I'd try that out...

err, I meant 1003 is already used, doesn't this has to be changed? How much bigger does the .exe get BTW?

the 1003 already being used isn't really a problem because it's used in a different dialog, but if it bothers you, you can change it to whatever you want (it *is* a #define after all :p)

I don't know how much bigger it makes the exe, probably not much, the majority of the code was just moved out of WebBrowserChrome.cpp, then there's the resource for the dialog boxes...

Hi Brian, hope you get an e-mail with this message:
As you already proposed a nice looking patch. Would you be interested in becoming a Kmeleon developer, commiting this (and hopefully other) patch(es)?
If so, let me know: Sebastian@SSpaeth.de
