Pwnboxer- Round Robin Problem

[RestrainT]

Hi, i recently got Pwnboxer and I have just made a Round Robin bind, To do following:
Press Shift-4, 1 Round for each game. When I press Shift-4 Ingame my main press Shift-4 each Round, but my slaves works fine. And when I am done hes shift key gets bugged up so its constantly held down. So when im pressing 1 or 2 my main guy only will press Shift-1, Shift-2. This bug goes away if I click on my desktop and back to the main's window, but gets so annoying when it gets bugged every time I use a Round Robin Bind. Can anyone help me with this problem? thx.

Not too many people use PB here.
If you go to multiboxing.com, there are quite a few users who can likely give a bit more support.

Maybe someone will respond who uses PB, never know.
