npde 2.0

Q. (Windows) I get the following warning when I try to display a help page
Warning message:
No CHM help for 'npde' in package 'npde' is available:
the CHM file for the package is missing in: print.help_files_with_topic("C:/PROGRA~1/R/R-25~1.0/library/npde/chm/autonpde")

A. Frankly, I have no idea what this message means and the online help was less than helpful. But apart from being a visual annoyance it has no influence on using the package itself. Any help to change this is welcome.
