My UI defaults are causing problems.

Whenever I mouse over onto a clickie in my bars, it overrides my attack [using stick and mouse]. So I end up standing there in the middle of melee looking like an idiot before I realize I have to move the mouse cursor off the bars so I can attack. Same issue if the mouse cursor is left in any window - chat, examine, map, etc.
I TRY to remember to move the mouse cursor back into "free space" on the screen, but its hard, esp when I'm in combat and the adrenaline is pumping.

Anyway to fix this? I tried changing the attack key from "right mouse" to a letter on the keyboard. Same problem.
