PP4/Win98/PWS Installation Help?

I just installed PHP4 onto my laptop with Personal Web Server/Windows 98 and when I try and access any local ".php4" page through IE5 I get the following message: CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are: This message is preceded by a Windows "This program has performed an illegal operation and will be shut down" dialog box. That box is titled "PHP"--so I gather that PHP.EXE is not happy with something in the install... Anyone know the quick answer? Any help would be appreciated... -- Mark Guildenstern: Pragmatism?
