Mank, it might help if you could determine whether the WoW's are running slowly or whether they aren't getting allocated CPU time. You might be able to tell by watching the processes tab of Task Manager as they run and keeping your eye on the CPU column. Ideally System Idle Process should have the highest number in that column followed by the two WoW's. If a third process is higher than the WoW's, I would shut it down. If the WoW's have very high numbers that's a sign that they are running slowly rather than getting squeezed out by some other process.
