A few days ago I made a post in software thinking that Keyclone maximizer wasn't working right. This was not the case.

Sometimes, when I open multiple WoW windows only the first one I open will be shown using the cpu. Task manager will show the first at around 50% cpu and the other 4 at 1-2%. This can happen regardless of how the windows are placed, what the settings are, whether the windows overlap, etc. I run all windows on one monitor with one video card. The odd part is that the windows showing no cpu usage work just fine unless I am in combat, at which point something very strange happens.

The framerate drops a bit but nothing major, the mouse pointer moves very slowly and jumps a little like it is stuck in mud, and my keystrokes stop registering. In the first few seconds they just register more slowly but it eventually takes 6-7 presses and 8 or so seconds to get anything to come through, even on the main window. During this, my cpu usage stays around 50%. I just don't get this and if anyone has an idea I'd love to hear it.
Thanks!
