After two days of running 2.7.3 Pro, it ate up almost all CPU resource. GUI response was terrible (throughout the OS)

Exiting Limewire solved the problem (after a while) mem slowly dropped from 35 MB downto 30 and after that it was almost instantly removed from the task list.

Btw. did previous Limewire versions also take up this much mem? It's using 28.5 MB right now :-(
And it's running as a leaf...
