PHP Manual CHM Edition: Many pages not found

Hi, I'm one of those very frequent users of 'your' php manual, and a happy one, at least in general :) I've just downloaded version 5 and unfortunately have come accross some issues, or basically one issue with many pages. The PHP Manual (yes, the second one), Preface and for instance some of the mysql_functions amongst many others just give me one of those 'helpfull' IE error messages: "the page not cannot be displayed ". I haven't noticed this in my old version (can't recall which one that was-relatively long time ago) Now I must admit that I've just installed winXP, so who knows perhaps the issue is at my end... For those of us that are stuck with a Win (or lose.) platform we do try to get used to this. :) Nevertheless I'd thought to bring the issue to your attention in the hope there's an easy fix you can help me with. Ironically the "missing stuff" item as well as all "About the manual" including the credits produce this error. This should really bother you. Great work anyhow! Jelle
