you know I just checked, and with limewire off my cpu usage is almost nothing but with it on it can go right up to like 90% depending on whats downloading (I think).

However I tried those fixes (the first two anyway) and downloaded and installed java 1.5 and they didnt make a difference.

Im also getting some 'disk problem' messages in the download window. I dunno, but this 4.9.9 version seems worse than the previous version.
