I see you double-posted. Crashing is something LW can't handle. I've never had the issue of a system crash whilst LW was open & my downld preferences became corrupted. This is a common issue for windows. But when it happens, you have to start from scratch as you found out. It doesn't matter what file size/% downlded, the downld preferences won't recognise the previous downlding efforts. There's nothing you can do except resume them at 0%.

The only times this has happened to me was when I jumped back to an earlier version of LW.

BTW be very aware that ALL OS X programs use Virtual Memory (VM). And if LW's been on for a couple of days or more then the VM increases dramatically. Closing LW will immediately recover the HDD space.

BTW if you have OS Tiger, then get Java 1.5 as it's supposed to be much more VM efficient than Java 1.4.2
Quoting Stief: with the latest java update for Tiger, you can tell the system whether to use java 1.4 or 1.5 http://docs.info.apple.com/article.html?artnum=301073
