I believe I have the 1.4.2 java beta. I will download the final and let you know what the effect is.

LimeWire runs fine for a time. Up to an hour. Then the entire machine starts locking up for about 30 seconds, the fine for 30, locking up for 30, etc.

In the past, I have been able to just kill LimeWire and things settled down. Not with 3.3.3. I have had to re-boot.
