CGI mode still requires php4isapi.dll?

On my development PC, if I do not have php4isapi.dll in my PATH then I get 500 errors from PWS. I have PWS running on Windows 98 SE, and am running PHP in CGI mode per the Script Map registry entry (running PHP.EXE). As soon as I move php4isapi.dll into the PATH it starts working. Why is this DLL required? Do I have something configured incorrectly? I should note I do see one other oddity on my PC...if I access any PHP page, I get a GPF on Windows shutdown. If I open no .php pages (i.e. PHP never runs), I do not get the error. (This is bug report #13396 in the database.) I have encountered this problem for the last few versions of PHP, but just with installing 4.1 did I notice that I had php4isapi.dll in my PATH from previous versions, leading me to wonder if PHP was still somehow running in ISAPI mode. - Steve Yates - SRT Enterprises - Do files get embarrassed when you unZIP them? / Taglines by Taglinator - www.srtware.com /
