Every so often when I click a link in this board, my browswer just downloads th page as a php file to my downloads folder. It doesn't try to render it or anything. I'll click the link again without doing anything different, and it loads just like it was supposed to. What gives? I've seen this in Safari, Camino, and Firefox on Mac. I haven't test on any other platform, but i thought i'd see if anyone has a clue.

Yep! I'm getting it lots today too. FFox 1.5 on a Mac.
