Help with MouseEnter and MouseLeave?

I have this script, and it works fine, but when I hover over it too quickly, it stays on mouseEnter until I put my mouse on it again to fix it. Any help?

framebutton.MouseEnter:connect(function()
active = true
	local keyConnection = framebutton.MouseLeave:connect(function()
		open:TweenPosition(UDim2.new(-0.07,0,0.51,0),EasingDirection,EasingStyle,float)
		active = false
	end)
	open:TweenPosition(UDim2.new(-0.05,0,0.51,0),EasingDirection,EasingStyle,float)
	repeat wait () until active == false
	keyConnection:disconnect()
end)
