I, too, have the crashes whenever I click outside the Gnutella window on my new white iBook: 9.1, 384MB RAM. I'm using version 1.8b. In my case, the crashes happen with a window which refers to "Error of type 2 made Limewire unexpectedly quit..." and, as w/an above complainer, when I click the finder.
I found this "solution" at one FAQ site for Limewire:
"Disable the context sensitive menu extension from the Help menu."
Well, there IS no "context sensitive menu extension" in the Help menu.
Is there any reason to think that downloading version 2.0 will help this problem?
