1) to include MFC42.DLL that you provided at the address 
<http://www.httrack.com/splitted/mfc/mfc42.dll.zip> 
into any Winhttrack setup file!  
MFC42.DLL must be stored in the Winhttrack root directory 
(...\Program Files\Winhttrack\) right during installation 
in order to fix definitively the "Ordinal Not Found" bug  
(message) found during any Windows installation (I tested 
on both NT and Windows 9x).

2) to clarify confusing Set Options->Scan Rules menu inbox 
content by including a compact sample for most used cases, 
like grabbing only one type of files starting from a 
website page.  Now is very hardly to find how to complete 
cause there are too many includings and excludings phrases 
that box we find here.  As sample, if want to extract only 
bmp wallpapers from a all other deeper links hosted or 
linked from a webpage or website root, have we to specify 
all type of files or links as excluded or how else ?   

Keep going for the best robot I've ever seen on the Net !
