Some thread problems

[Manifest0]

Greetings!

I'm having trouble closing phex.
Now everytime i try to close phex, it freezes... Also i can't download.
The downloads start at an amazing speed, and then goes to the xxxbytes. I've a lot of candidates from who i'm downloading (well it's what the status says), but i'm not downloading!

(i've to cut some errors... The text was too long. The Error/phex.download.MemoryFile:: appear a lot, a really lot of times! (about 220000 chars more than the forum limit for a post!))

A NIO exception...
