Extension Load Error

Ok, here is another extension problem. This one has me stumped. I have the 4.2.3 (Sept. 6) binary release. I have it installed and working properly with Apache 1.3.24. All the DLLs are in the correct directories, phpinfo() works, ect. But, when I try to load an extension it returns the error: (For example the imap extension): ---------------------------------------------------------------------------- -- imap: Unable to initialize module Module compiled with debug=0, thread-safety=1 module API=20020429 PHP compiled with debug=0, thread-safety=1 API=20010901 These options need to match. ---------------------------------------------------------------------------- -- Obviously, the APIs don't match, but they were included in the release. Am I the only person getting this error, if so I would assume that I have done something wrong, if not it must be the dist. Any ideas? Should I just try an older distribution? BTW: The OS is WinXP SP1
