Hi there!
I'm running aMule version 2.0.3 in a Ubuntu Hoary, and I have a similar problem. Anytime I try to do a global search (not a local search), aMule hangs and I can't kill the Amule process or anything. Only aMule hangs, my ADSL connection still works after the crash and I can use any other application that requires Internet access.
I don't know if the problem is because of the number of results the search returns, or because any other reason, so any help will be sincerely appreciated.
Thanks in advance!
