    What problems do you have ? Be more specific, because "highgui.lib is making problems" is too general.
    You may try to search the forum for "OpenCV windowsXP" or sth.
    Tell us how did you build the cv libraries, if you are using CMake, then some time ago I've posted a message about OpenCV compilation on WindowsXP, here is the link : link ( basically try to disable SSE support ).

    That's what I meant, disable SSE support while compiling OpenCV with gcc.
    Show the code where it crashes.
    Btw. when using Qt you have more nice ways to show an image than "cvNamedWindow"
