Accessing MS Word errors

Hi All I hope someone can help me I am trying to open Word using: $word = new COM("word.application") calling Word methods to add a couple of lines of data, then saving the file. I am using PHP v4 XP with IIS 5 and php.ini PHP installed directly with its installer. The script appears to open word as it appears in the processes. Error message: 1. php.exe has caused a problem and will close. (standard windows) 2. In browser : Specified CGI application is misbehaving by not returning a complete set of HTTP headers. Any pointers or help will be gratefully received. Ken ken@diamondsoftware.co.uk
