after all, OS is software.. but anyways. does this happen with your system ?
1. burn something with Nero
2. leave it to "burning finished" (or whatever there reads when its done) state
3. let your computer crash.

on step 3 I didnt use the comp at all, I'm not sure if it has to be that way. time it took was more than 3 hours according to my irc-logs but.. would be of great help if I could say to MS that it happens on other ppl's comp and maybe we could get them to fix it :) and, this would tell me if its just my system :( (as for me, it happened also when I had burned with Alcohol 120%)
also, one thing - I havent been able to get my system to make up a memory dumb. not in any size. the ppl at MS requested full memory dumb. it this happens and you manage to get that dumb file, let me know :)
