1. I presume the 1st problem only happens with some files for you. I just tried quitting LW with a file at about 60%. Then I rebooted & about 2 hours later started LW & the same file started where it left off immediately from 4 hosts until completion. Did you try deleting your Prefs folder?

2. I thought stopped downlds always retained the incomplete file. If a file stops downlding I'll stop it & reselect it from the search results & it starts where it left off. Or perhaps I'm misunderstanding your issue here.

I did notice when I re-opened LW 4.4.5 it closed again during the loading interface/resources stage. But that's not necessarily a bug (could be my win 2k system which works at about 15-30 MHz at a guess. lol) I'll monitor future openings. Ah didn't happen the next time after rebooting.
