minimize backpacks problem

[popit]

hello i have a Lua for backpacks to be minimized i use but sometimes when i look back at tibia it says "do you want to leave tibia?"
never happened before i added this backpack minimize i have it saved as a seperate lua named *Backpack minimize* that i load with my scripts
anyone have a clue why its causing the message in tibia to come up asking if i want to leave?

dofile("Forgee.lua")
registerEventListener(WALKER_SELECTLABEL, "onWalkerSelectLabel")

function onWalkerSelectLabel(labelName)
if (labelName == "BackpackReset") then
setWalkerEnabled(false)
resetBackpacks()
setWalkerEnabled(true)
end

local indexes = Container.GetAll()
for i = 1, #indexes do
Container.New(indexes[i]):Minimize()
wait(400, 800)

end
end

minimizeAll = true --set to false if you only want to minimize specific containers
minimize = {"Camouflage Backpack", "Beach Backpack", "Brocade Backpack",} --specify the container names of the containers you want to minimize (only used if minimizeAll is set to false)
hideEquipment = true --set to false if you don't want to hide equipment
waitTime = {200,400}


--don't change this line! \/--
if(minimizeAll) then minimize = Container.GetIndexes() end --don't change this line!--
--don't change this line! /\--

while(true) do
if(hideEquipment) then Client.HideEquipment() end
wait(waitTime[1],waitTime[2])

for i=1, #minimize do
if(minimizeAll) then cont = Container.GetFromIndex(minimize[i])
else cont = Container.GetByName(minimize[i])
end
cont:Minimize()
wait(waitTime[1],waitTime[2])
end
end

I use this to minimize my backpacks. It's good because you can minimize them all, or choose specific backpacks if you only want your gold backpack, for example, minimized.

anyone can help me? sometimes when it reaches BackpackReset label it doesnt minimize all backpacks sometimes it minimizes no backpacks, sometimes it minimizes 1 backpack, sometimes it minimizes all backpacks and sometimes when i look back the bot is running around with "are you sure you want to leave tibia?" on the screen like its trying to exit tibia xD only happened since i added this minimize to my script and i need it cause i need more room for bps of loot hehe
