Latest Limewire 4.8.1 is causing slowdown of all activity on computer. Althougt others may have a virus or trojan issue, this is not the case. I have up-to-date NAV and test and scrub weekly as well as spyware detection and scrubbing. Using XP Windows Task Manager (called with CTRL-ALT-DEL) shows spikes of high CPU usage (sometimes to 100%) with Limewire running, and the Processes Window shows it is Limewire conuming the cycles (shown by sorting according to CPU useage column). Even with limewire "Disconnected" and no uploads or downloads indicated the problem still exists with exactly the same symptoms. The problem manifests itself by slow activation of other windowed programs, mouse cursor freezing periodically, and periodic sections of garbled music if listening to Limewire player. Music is also peridocially garbled if listening to music with Winamp or other players. HOWEVER: If Limewire is COMPLETELY shut down (not just minimized) then the CPU cycles are suddely freed up, the mouse does not freeze, other windows applicaitons activate instantly, and Winamp and other players no longer periodically garble the music. This issue is clearly related exclusively to the fucntion of Limewire running. Ideas?
