WIN32 problem

My webhost has updated to 4.0B2 and some code is breaking from 3.0 I downloaded the 4.0B3 win32 binaries for my development system. I am using 98 and PWS. I installed them and where this URLS used to work: http://localhost/php/php.exe?c:/webshare/wwwroot/test.php3 I now get this error. Fatal error: Unable to open C:\WebShare\wwwroot in Unknown on line 0 ----------------------------------- So, I tried the direct approach: http://localhost/test.php3 and I got: ---- PHP caused an invalid page fault in module PHP4TS.DLL at 016f:100489f6. ---- ...after which my browser shows: ---- CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are ---- that's not a typo, there is nothing returned. Any ideas? What do I look at? ---------------- John-Marc
