Getting Low Frame rate at combat!

Hi All,

Just find this site and totally loved it and bought another wow acc to give a try to multi boxing. Its been 2 days since i first start dual boxing with my 2 locks but i have a starnge problem... ?( When i get in combat the frame rate just drops to 20 or smthg like that and the screen stops like every 0.5 millisecond just wierd, :cursing: but when the combat ends both screens FPS goes up to 60 FPS. Im using single PC and 2 seperate screens 19" sony LCD and a 17" ctx CRT monitor. Fisrt wow plays in 1280x1024 with full graphics and the second 1 in 1024x768 minimum graphics and no sound. Any ideas is it about the multiboxing software or my Pc cant handle it! ty for ur answers... (WOW accounts are in diffrent directories even in diffrent hard drives :D )

Multi boxing Software : Keyclone 1.8f
PC Specs : Intel QX6600 Quad core 2.4 - 4GB 800 MHZ DDR2 - Asus P5KB Board - MSI 8800 GTS 320 MB - with 2 screens.
