ok i found the same button in windows xp
download chm help ... it will donload manual_de.download or manual_en.download
rename it to manual_xx.chm
right click it and open properties
unlock it with the button
(i never saw this button before in my whole life
)
in the english manual you go and read from begining to end
in the german manual you go and read until chapter 3
and from there to the end it will be in english and not german
i also found the manual in the file directory of codeblocks in the docs directory
its also a chm file and in english and it works without any problems
