Can't you 'draw out' other columns wiht the mouse?
Also: any idea why the Object Browser background is BLACK in you screenshot? What Windows theme are you using? Do you have some aditional 'theming software' installed?
Object Browser background is BLACK because it is selected in “Change Color Object Browser …” option. I tried to change the color, but the result is the same.
My themes are the standard Windows and I have not installed any additional software themes.
