hmm, same behaviour here.
i didn't exactly know what i did,
but from one moent to the other, i had the same problem.
i am using quick reply, but that already for a long time, not since today.
if i turned off javascript, i could load the page with no problem.
After closing the browser and starting again,
now everything works normal, with and without javascript.
So i can reproduce this problem again.
Browser Mozilla Firefox 1.0.4
So i posted just for information, maybe other users have such problems too.
