ok , the problem is happening to me many times on a lot of ubuntu desktop 8.04 servers .
i installed utorrent exactly as this :
1 - went to : www.winehq.org
2 - installed wine from above .
3 - opened firefox , downloaded utorrent and installed it .
nothing else i did , but still the same bug appears .
from what i noticed , it only happens when i connect to many connections ... so i assume it's a connection limit problem ... i followed many tutorials after googling but couldn't find a solution .
if anyone has a solution please let me know , i hate paying for windows for this small bug which really annoys me .
