Iexplore - php - frames problems with javascript

Hey there. I am having a major problem for the moment with Iexplorer and php.. I have tried to run the webpage in OPERA and it does everything it is suppose to.. I have this problem that when i want to assign a function to a button which should open new pages in 2 frames (i do this by a javascript function) it refuses to launch the php page in its window. It only sits there and acts as if it doesn't find the page. When i run the php page in a non framed environment it works fine. I have this function which Iexplorer seems to have problems with changeframes(navigator,content) parent.navigator.location.href=navigator.html parent.content.location.href=content.php I am not sure if there is a way to make the frame refresh itself. Is there a function predefined in javascript which can refresh a frame? It is so frustrating because OPERA displays the webpages and the frames beautifully, but iexplorer 5 fails to do so. I would appreciate any help to solve this problem and i do realize it is not specifically for the windows-php list, but thanks anyways Lars
