WoWInterface - (mMenu) after Loading screen function doesnt work anymore

Hey there
today i published my first Addon mMenu:

http://www.wowinterface.com/download...oggleMenu.html

Unfortunately there's a bug: When i open the menu .. and get a loading screen (test it with mage teleport) - the menu is still open and when i click the "m" button .. the border around the addons disappear but the addonbuttons are still there.

It doesnt make sense to me cause:

Code:

openmenubutton:SetScript("OnMouseDown", function()

        if not IsShiftKeyDown() then

                if menu:IsShown() then

                        menu:Hide()

                        openmenubutton.texturemo:SetAlpha(0)

                        openmenubutton.texture:SetAlpha(1)

                        if IsAddOnLoaded("Recount") then recountbutton:Hide() end

                        if IsAddOnLoaded("TinyDPS") then tdpsbutton:Hide() end

                        if IsAddOnLoaded("Skada") then skadabutton:Hide() end

                        if IsAddOnLoaded("AtlasLoot") then atlasbutton:Hide() end

                        if IsAddOnLoaded("Omen") then omenbutton:Hide() end

                        openmenubutton:SetBackdropColor(unpack(configBackDropColor))

                else

                        menu:Show()

                        openmenubutton.texturemo:SetAlpha(1)

                        openmenubutton.texture:SetAlpha(0)

                        if IsAddOnLoaded("Recount") then recountbutton:Show() end

                        if IsAddOnLoaded("TinyDPS") then tdpsbutton:Show() end

                        if IsAddOnLoaded("Skada") then skadabutton:Show() end

                        if IsAddOnLoaded("AtlasLoot") then atlasbutton:Show() end

                        if IsAddOnLoaded("Omen") then omenbutton:Show() end

                        openmenubutton:SetBackdropColor(unpack(mouseoverBackdrop))

                end

        else

        openmenubutton:ClearAllPoints()

        openmenubutton:StartMoving()

        end

end)

As you can see this manages to show or hide the menu .. so i click ->
menu:Show() .. that works. But all the other stuff like

Code:

if IsAddOnLoaded("TinyDPS") then tdpsbutton:Show() end

doesnt work.
Why?

Oh and with /rl the menu is hidden on start cause i type a menu:Hide() above the CreateFrame. If i put the menu:hide into the player_entering_world function, the menu is hidden butt .. not the buttons :/

hope u can help me
