You know, I was about to say 'No, I haven't installed any new media players recently.' However, I have just started getting messages from RealMedia when I first boot up, and coincidentally, it seems to be about the same time as this problem started. Do you think that could have something to do with it? (I've often had problems with RM stuff in the past. Not sure why it started showing up again,but I'm going to go get rid of it.) As for your other suggestion, yes, I did re-render a 30+ movie last night, and it worked fine (again, as it did the first time before this started), but then I tried a new movie, and got the same problem of it just stopping on the final frame... Another question: where do these partially completed files go? I started a frame by frame job, got to about frame 80 of 200, then 'apparently' ran out of disc space. Where did those 80 .psd files go? Also, in the past I had been able to stop an AVI job in progress, and I would get the AVI file up to that point. No longer though... Thanks for any and all help! :)
