after some (very time consuming ) research I found out that there must be some special handling of Win Builder 075 beta 4 concerning the Title entry in the Main section. I wanted to add the program ImgBurn to my VistaPE project, but that script never showed up in Win Builders project tree. Using Process Monitor I noticed that the script file was found and that the first 256 bytes of the script file were read, but nevertheless it was not listed.
When I changed the title from
[Main] Title=Img Burneverything was fine.
Have I overseen in Win Builder's documentation that this title is a reserved word and shall not be used, was it forgotten to document it or is it simply a bug?
