QF/C: arrayrenderer - different results on linux/windows. how can this be? uh..

Hi! I am using the default QuickForm Array Renderer. On my two boxes it produces the following datastructures and assigns it to the template engine, but I cannot really understand why it does this, because basically its the same code and both machines run the same pear pack versions. LINUX - an array ["attributes"]=> array(4) {

    ["action"]=>
    string(9) "/core.php"
    ["method"]=>
    string(4) "post"
    ["name"]=>
    string(5) "page1"
    ["id"]=>
    string(5) "page1"

} WINDOWS - a string< array(7) { ["frozen"]=> bool(false) ["javascript"]=> string(0) "" ["attributes"]=> string(64) " action="/foo/core.php" method="post" name="page1" id="page1"" why does the same code produce an array on linux and a string on windows? i have really the same package versions and the same code. /m
