I have exactly the same problem using V4.14.3 and multiple downloads (3 or 4 ) using an AMD Sempron/NT200/SP4. The machine suddenly runs slow and processor usage goes to 97-99% and stays there.

This makes it difficult to shut down Limewire and makes the machine unuseable for multi-tasking.

I tried previous versions V4128 and V41211 but they were exactly the same.

Can someone from Technical Support please confirm that this is a known bug ?

Regards,

Ian
