in reply to perlman.pl only works in the debugger under cygwin

This looks like some fairly crusty old code. You probably are better off with the suggestion of using something else. Nevertheless, I am curious. Do you get any information running this script with warnings enabled?

    There is only one warning:
    "my" variable $section masks earlier declaration in same scope at perl +man.pl line 179. Scouting man directories Starting UI ...Use of uninitialized value $id in hash element at /usr/ +lib/perl5/vendor_perl/5.10/i686-cygwin/Tk/After.pm line 39.
    etc.

    Removing the second my declaration does not change the result (nor should it, looking at the code).

    I am puzzled as to how the debugger "fixes" the code. The implication from error messages is that an undefined value is being used where it is not permitted; how can the debugger fix that? In fact, it shouldn't. The reason I even tried the script in the debugger was to see where the problem was and to try to fix it.
