How to access Expression Box

[Anonymous]

Here is my strange predicament. I was creating a straight table and in the process when I was trying to add an expression, the box jumped and hid away to the top right of screen as in the image below. I tried dragging it. not successful. Can someone suggest how to get the expn back at the center to start working on it?

This happened to me when using multiple screens/monitors (extend / duplicate) ...or at least when your notebook thinks there is another screen to the right.

I guess you have some kind of control button on your notebook or a ctrl panel somewhere: try to select something saying like 'Disconnect Projector'
