Here's a more serious problem. After I killed the hung limewire process earlier and reran it ... nothing. As in, no downloads. No message saying it couldn't restart them either. Closing and restarting didn't fix it, despite the half a meg downloads.dat in the incomplete directory and the downloads.bak for it to fall back upon.

Losing the downloads that resulted from searches isn't a big deal, since they'll turn up again eventually with the same searches. But ones that resulted from host browsing may be difficult to find again indeed.

This needs to stop happening. Limewire hasn't been reliable about preserving your downloads across sessions since version 2.something. The 3.somethings were especially bad for losing data in this manner, but the 4.somethings are only somewhat better...
