File will not close.

[Shurlock]

Hi, can anyone tell me why the file that is being read and closed will not let itself be deleted?
Manual delete will create an error 'The file is being used....".

A similar script in another function works perfectly.
Only difference with that other function is that this file should only be deleted if vUser is online and has been sent the message (WatchMess)

function CheckWatch(curUser)
	local WatchFile = "Watch/"..curUser.sName..".txt"
	local MessSent = 0
	if readfrom(WatchFile) ~= nil then
		readfrom(WatchFile)
		local line = read()
		local _,_,tmpOP,tmpDate,tmpReason = strfind(line, "(.*)|(.*)|(.*)|")
		local vUser = GetItemByName(tmpOP)
		if vUser then
			local WatchMess = "\r\n\t*** On "..tmpDate.." you have asked to watch the arrival of "..curUser.sName
			WatchMess = WatchMess.."\r\n\t*** Reason: "..tmpReason
			WatchMess = WatchMess.."\r\n\t*** The user has just entered the hub. :) "
			SendPmToNick(vUser.sName, BotName, WatchMess)
			MessSent = 1
		end
	end
	readfrom()
	if MessSent == 1 then
		remove(WatchFile)
	end
	return 1
end

Any help is appreciated!  Thnx.
