Hotkeynet renaming windows but sometimes missing one

[Xeder]

So basically, I have a script for either 5boxing or 8boxing. I had some problems with it failing to rename some windows so I went the route of:
Open Hotkeynet > Open 5 or 8 wow windows > start Hotkeynet script and continue with multiboxing.
This works most of the time, however from time to time, the wow window that is "clicked" as in "main one currently" is renamed back to "World of Warcraft" instead of wowx and therefore all the commands are not sent to it. To solve that I usually just close all windows and restart, but it gets kinda irritating to reopen all of them again. Is there any solution to this problem?

My script is as follows:

//================================================== ==============// SAMPLE SCRIPT FOR TWO WOW'S ON ONE PC
//
// Instructions: Copy this entire script (all the blue writing
// on gray background including comments). Save it in a file.
// Load it into HotkeyNet.
//
// Toggle the scroll lock key to turn hotkeys off and on. (You
// can change this if you want, just like you can change
// everything else with HotkeyNet.)
//
// Requires HotkeyNet build 147 or higher.
//
// For more info, go to www.hotkeynet.com
