Hey Kivrus

I had problems with getting it working too cos I didn't quite understand the whole "Hidden windows" thing, but you're right, you need to launch the code to rename the windows twice, then the code to name it back to normal once, I haven't had issues since doing that.

I eventually added it into my script instead so it runs the rename twice and renamed back once in 1 command, looking like this

//-----------------------------------------------------------
// PRESS CTRL P TO RENAME WOW'S IF YOU LAUNCH THEM MANUALLY
// PRESS CTRL L TO RENAME WOW'S BACK TO NORMAL
//-----------------------------------------------------------
<Hotkey ScrollLockOn Ctrl P>
<SendPC local>
<RenameWin "World of Warcraft" WoW1>
<RenameWin "World of Warcraft" WoW2>
<RenameWin "World of Warcraft" WoW1>
<RenameWin "World of Warcraft" WoW2>
<RenameWin WoW1 "World of Warcraft">
<RenameWin WoW2 "World of Warcraft">


<Hotkey ScrolllockOn Ctrl L>
<SendPC local>
<RenameWin WoW1 "World of Warcraft">
<RenameWin WoW2 "World of Warcraft">
CTRL P to rename and get going, CTRL L if for whatever reason I need to name them back, I adjusted it for 2 clients since you said you run with 2

If this doesn't help, then it's beyond me, I'm fairly new to all this, hope it helps.
