Using WindowsMe, PWS and ActiveState Perl (ActivePerl-5.6.0.623-MSWin32-x86-multi-thread.msi)

Just tried to upgrade to 6 on my PWS and the ubb6_test.cgi ran fine.

ubb_upgrade.cgi then ran fine.

when I attemted to go to cp.cgi I got the following error.

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:

flock() unimplemented on this platform at C:Inetpubwwwroots9cgi-bin/ubb_lib.cgi line 243.

Do I need to upgrade my perl? If so how/where?

thanks,
jeremiah
