[wp-testers] Forced custom permalink structure with PATHINFO?

[HelixGalaxy]

Hi,

Downloaded the latest nightbuild and after installing I see that when I want
to set the custom permalink structure is forced on me with /index.php in
front?

Why and how can this be removed? Is it a bug?

It wasn't a problem some nights ago ...
Yes I run IIS on WIndows, but have no problem with mod_rewrite
compatibility.

Regards,
Martin
