php 4.1.1, apache 1.3.22 and windows XP

hi, my php 4.1.1 + apache 1.3.22 + windows XP combination is doing strange things. php is working fine (from the command prompt) and apache is ok with html pages. but when i try to load a php file with just the phpinfo() function - sometimes loads it and sometimes i get the 'The page cannot be displayed' message. further, other php pages just won't update when i refresh even though i have changed the source code. any help would be greatly appreciated. athene ***************************************************************** Contracting in London? 1st Contact can maximise your income! http://www.1stcontact.co.uk ***************************************************************** This is a confidential message for the named persons only.
