Doesn't work properly with double monitor

[MrSabaku]

I have two monitors and I only have the taskbar activated in one, when I try open the taskbar group a .net framework error show up and the taskbar group doesn't show properly, is anyway on the display, but ir works correctly when I turn the taskbar on both monitors. I leave the error script down.

System.ArgumentOutOfRangeException

Google translate part.

Cuando esté habilitada la depuración JIT, cualquier excepción no controlada se enviará al depurador JIT registrado en el equipo en lugar de controlarlo mediante el cuadro de diálogo.

When JIT debugging is enabled, any unhandled exceptions will be sent to the JIT debugger registered on the computer instead of controlling it through the dialog box.

Second this, program runs perfectly when Taskbar is active on multiple monitors, however doesn't work if Taskbar is located in one monitor only

Try unplugging your monitor, that fixed it for me.
