You should be able to fix that by calling "reinit()" in the child frame's onload handler. But note that this is also called by the frameset script when it's first loaded, so probably should have something like this (note the example should work with our frames sample, but I can't be sure about your particular setup):

if (!window.parent.first_time)
window.parent.reinit();

Add the above code in the body's onload handler for the child frame and you should be done. Please let me know if that doesn't work or if you have any other questions.
