#1220 Big 7.zip's window doesn't fit into the screen

[Otter]

I understand that 800 × 600 screens are shrugged as obsolete, but still there's no need to enforce a big screen. Because all (7_zip) information can fit well in that space. See what it displays (in attached file). It even enlarges the window while there's nothing on it. And tries to be exactly 600 points, and intersects with the task panel (even more so if task panel will be 2 floors). OK / cancel buttons, and title, are unvisible.
