I'm sorry, I forgot you're using two PCs. I wrote that sample as if you would load it and run it and press keys for it on the second PC (the one with the four toons). But you probably want to press keys to do those actions on your main PC. If that's the case, the file has to be written as follows, then loaded into HotkeyNet on the main PC. Fill in the IP address of the second PC where indicated.

Code:
<Hotkey Ctrl R>
<SendPC  SECOND_PC_IP_ADDRESS>
<Rename "World of Warcraft" wow1>
<Rename "World of Warcraft" wow2>
<Rename "World of Warcraft" wow3>
<Rename "World of Warcraft" wow4>

<hotkey F1>
<SendPC SECOND_PC_IP_ADDRESS>
<TargetWindow wow1>
<SetWinPos 0 0>
<SetWinSize 512 384>

<TargetWindow wow2>
<SetWinPos 512 0>
<SetWinSize 512 384>

<TargetWindow wow3>
<SetWinPos 0 384>
<SetWinSize 512 384>

<TargetWindow wow4>
<SetWinPos 512 384>
<SetWinSize 512 384>
