you guys... sheesh... that hooksecurefunction stuff does not make what you have put in the function capable of functioning in the secure environment. In other words just because you use hooksecure does not make it secure.

This is a chunk of secure code that runs the GrimUI context menu. It makes it so the context menu(a tray of buttons) can be shown/hidden in combat without taint.

local hotSpot = CreateFrame('Button', nil, UIParent, 'SecureHandlerClickTemplate')

hotSpot:SetHeight(16)
hotSpot:SetWidth(16)
hotSpot:RegisterForClicks('LeftButtonUp', 'RightButtonUp')
hotSpot:SetFrameRef("contextMenu", contextMenu)
hotSpot:SetAttribute('_onclick', [[
	local frame = self:GetFrameRef("contextMenu")
	if button == 'LeftButton' then
		if IsControlKeyDown() then
			control:CallMethod("ToggleMiniMap")
		else
			if frame:IsVisible() then
				frame:Hide(true)
			else
				frame:Show(true)
			end
		end
	elseif button == 'RightButton' then
		if IsControlKeyDown() then
			control:CallMethod("ToggleInfoLog")
		else
		control:CallMethod("ToggleCombatLog")
		end
	end
]])

In order to get around taint issues you need to use code like this for any kind of show/hide or reposition of secured frames. A secured frame is any frame bliz has decided you could use an addon to move around during combat in a method that would allow you to "cheat" action bars fall into this catagory, the bosstargetframes, the focus frame, item buttons, the mounted control frame, some others to including the worldmap frame in a strange way... having to do with the questblobframe.

here is another example, this is the GrimUI config button. made secure so it could toggle the micro bar and options windows while in combat, note however that even though the options can be opened in combat 90% of them will not function. You pretty much can not move around any secure frame during combat no mater how you code it.

local configButton = CreateFrame('Button', configButton, UIParent, 'SecureHandlerClickTemplate')

configButton:SetHeight(30)
configButton:SetWidth(62)
configButton:RegisterForClicks('AnyUp')
configButton:SetNormalTexture([[Interface\AddOns\]] .. addonName .. [[\Media\ConfigButton]])
configButton:SetHighlightTexture([[Interface\AddOns\]] .. addonName .. [[\Media\ConfigButton]])
configButton:SetPoint('BOTTOMRIGHT', addon.skin, 'TOPRIGHT', -2, 0)
	
configButton:SetAttribute('_onclick', [[
	if button == 'LeftButton' and not IsControlKeyDown() then
		local microBar = self:GetFrameRef("microBar")
		if microBar:IsVisible() then
			microBar:Hide()
		else
			microBar:Show()
		end
	elseif button == 'RightButton' and not IsControlKeyDown() then
		control:CallMethod("OpenConfig")
	end
	
]])


function configButton:OpenConfig()
	if addon.configPanel then 
		if addon.configPanel:IsVisible() then
			InterfaceOptionsFrame:Hide()
		else
			addon.configPanel()
		end
	end
end

Also here is some good functions for show/hide/lock frames to prevent the reappearance of pesky frames.

--[[-----------------------------------------------------------------------------
DoNothing - A simple dummie/do nothing function
-------------------------------------------------------------------------------]]
local function DoNothing()
end
addon.DoNothing = DoNothing

--[[-----------------------------------------------------------------------------
HideTooltip - Hide GameTooltip (several frames use this)
-------------------------------------------------------------------------------]]
function addon:HideTooltip()
	GameTooltip:Hide()
	self.tooltip = nil
end

--[[-----------------------------------------------------------------------------
HideFrame - Hide a frame, prevents it from being reshown
-------------------------------------------------------------------------------]]
function addon:HideFrame(reference)
	local frame = type(reference) == 'string' and _G[reference] or reference
	if type(frame) ~= 'table' then return end
	frame.Show = DoNothing
	frame:Hide()
end

--[[-----------------------------------------------------------------------------
ShowFrame - Show a frame, undoing :HideFrame behavior
-------------------------------------------------------------------------------]]
function addon:ShowFrame(reference)
	local frame = type(reference) == 'string' and _G[reference] or reference
	if type(frame) ~= 'table' then return end
	frame.Show = nil
	frame:Show()
end

--[[-----------------------------------------------------------------------------
LockFrame - Lock a frame, prevents SetPoint and ClearAllPoints from working
-------------------------------------------------------------------------------]]
function addon:LockFrame(reference)
	local frame = type(reference) == 'string' and _G[reference] or reference
	if type(frame) ~= 'table' then return end
	frame.SetPoint = DoNothing
	frame.ClearAllPoints = DoNothing
end

--[[-----------------------------------------------------------------------------
UnlockFrame - Undo :LockFrame
-------------------------------------------------------------------------------]]
function addon:UnlockFrame(reference)
	local frame = type(reference) == 'string' and _G[reference] or reference
	if type(frame) ~= 'table' then return end
	frame.SetPoint = nil
	frame.ClearAllPoints = nil
end
