However, if I knew how to do that, then I wouldn't be posting the question here and I would be working on it already

At http://aspn.activestate.com/ASPN/Mail/ you'll see there's a libwin-32 mailing list. It's all but dead ... but there's possibly still a few people subscribed to that list (eg Jan Dubois) willing and able to help with the problem.

Alternatively a simple bug report, without any proposed solution, to either rt.cpan.org (as tye suggested) or a Bugzilla report (see http://bugs.activestate.com/help.cgi) might prove fruitful. Jan Dubois is closely associated with fixing bugs in both ActiveState and the libwin package - but it's probably more appropriate to file your report with rt.cpan.org as it's really a libwin bug (rather than an ActiveState bug).

Cheers,
Rob
