No joy with a clean test Apache install, so I took at look at the 
rewrite logs.

This showed something. Starting at Main/Home and going to the sandbox - 
which works - yielded:

add path info postfix: C:/Documents and Settings/Marc/My Documents/My 
Website/pmwiki/Main -> C:/Documents and Settings/Marc/My Documents/My 
Website/pmwiki/Main/WikiSandbox

(This is only the first line of the rewrite log.)

Returning to Main/Home and going to PmWiki/DocumentationIndex yielded

add path info postfix: C:/Documents and Settings/Marc/My Documents/My 
Website/pmwiki/pmwiki.php -> C:/Documents and Settings/Marc/My 
Documents/My Website/pmwiki/pmwiki.php/DocumentationIndex

Note how, in the latter case, the PmWiki group name has changed to 
pmwiki.php. And, of course, the URL is no longer going to find its 
target.

By way of comparison, here's the result of going to 
PmWiki/DocumentationIndex from a farm wiki home page.

add path info postfix: C:/Documents and Settings/Marc/My Documents/My 
Website/pmwiki/marc/PmWiki -> C:/Documents and Settings/Marc/My 
Documents/My Website/pmwiki/marc/PmWiki/DocumentationIndex

So it seems that something is changing PmWiki to pmwiki.php in the URL 
before the rewrite process begins. (This occurs for all pmwiki group 
URLS and no others.)

Any ideas?
