Thank you for replying. Yes, the start and default names are the same, which I understand is why <filename_1> is generated. (We can't change the filenames now.)
I did generate lower case one time, but have cleared the "generate lower case" check box as we need initial caps.
When I generate webhelp:
- start and default should both be initial caps: <Apphelp> and <Apphelp_1>
- Instead, start is initial cap, default is lower case: <Apphelp> and <apphelp_1>
Why isn't it generating both file names with initial caps?
Sigh. Answer is embarrassingly simple. May as well laugh! Project had been renamed to upper case; default topic name had not been changed.
