Grrrr!  One of my renders for the challenge has frozen at the antialiasing phase. 0% for the past hour, at least.. At least that's what I discovered when I woke up this morning... maybe for more hours. Any clue how to continue it?

It wasn't being rendered in my farm, maybe I should've done it that way. Computer is an AMD Turion 64 X2 (dual core) with 2 gigs ram, 200 gig HD (so it's not like... running out of HD space if it needs it). Rendering for about 6 hours then... 0%... still 0% antialiasing even as I type this... Task manager reports B6.1 has not frozen... it's responding.. i can stop the render, save the file, etc, and continue, but it doesn't get past the 0%. Any idea?
