Hi,
I tried to reassign this bug to Eric Pouech:
http://bugs.winehq.com/show_bug.cgi?id=1513
however it says I can't CC or reassign it to him as the email address I used, pouech-eric@wanadoo.fr, is not a valid bugzilla account.
Basically, the guy has some details on the undocumented parts of how the winhelp protocol works......
thanks -mike
