PHP4.0.5-RC1/IIS5/ISAPI [Q] Should I report problems?

Hello all. I installed PHP4.0.5-RC1(from www.php4win.de) on IIS5 using ISAPI. It works for simple scripts, but it gives A LOT of problems for complex codes, blank screen, access violation message, missing functions, etc, on my Window 2000 Server SP1/Japanese. It also works really slow. (I can see characters are written one bye one on my browser) Question is: Should I report these problems or ISAPI is considered as alpha quality(?), so I should forget about it? I haven't used PHP on Windows much, yet. If I use PHP on Win and report these problems, I'm sure it will be a long lists. Am I only one getting a lots of problems with IIS5+ISAPI? -- Yasuo Ohgaki
