RobotStudio event

Window to switch operation mode has disappeared

Hello

As I was using the teach pendent in RobotStudio I have moved the window to switch the operation mode on my screen by drag an drop. When I droped the window it didn't stop moving and moved out of my visible screen. At that time I was working on two screens. But the window was not on the first and not on the second screen. What can I do to get the window for changing operating mode back? I am using RobotStudio 4.0 Build 2461 on Windows XP Pro. I just have the TeachPendant and the Joystick Window. Closing and opening of RobotStudio does not help.

Thanks for your help.
