Window Auto-Focus

I know its not always the best way to do things and I think this is prob a feature in windows xp itself that I need to enable but How can I make it so I simply move my mouse pointer over to another window and only have to click once to do a click action in wow....for example...I want to go over to my shamans wow window and click first aid to make some bandages but I have to click twice (once to change my focus into that wow window and a second time to click the first aid button)....Can i enable something like auto-steal focus in windows to do this or?

I believe KeyClone does this automactly using maximizer, not sure about the other mulitplexers tho ..

in keyclone:

CHECK keyclone/setup/general/focus-follows-mouse

Yea so this thread finally convinced me to buy key clone.....Now....I find out this feature is bugged ....If I leave this on it will cause me to be unable to move my mouse down to the second windows sometimes (it seems after looting in paritculiar). I am using maximizer. I searched the forums and the only solution i can find is "Turn off FOCUS-FOLLOWS-MOUSE"...I would really like to have this feature as its the main reason I purchased keyclone :(

Ok I am going to try to do it with a program called XMOUSE as someone suggested on the forums here

I installed "Powertoys for XP" (its on microsofts site, you can google for it) and it lets me set XP so that just mousing over a window sets focus to it. Takes a bit getting used to and Ive yelled at my PC sometimes, but works nicely for mboxing.
