No, why? If it's because you do not have one of the newer intel machines & Leopard OSX 10.5 & cannot run LW 5, don't worry. LW 4 is much better at present anyway.

See note at top & bottom of this post link: http://www.gnutellaforums.com/mac-os...ck-lw-4-a.html

Personally I generally run LW 4.16, and most experienced users have gone back to LW 4.
