As shown in the screenshot attached, there are two problems in setup position with Windows Vista:
1. the button that is supposed to surround "White" does not appear
2. The counter for move number is too small and one has to scroll to see the number.
We already had problem with (1) in the past, and probably the behavior might depend on both the OS (Linux, WinXP, WinVista, ...) and Qt version. A solution might be to have there (instead of the button) the two small boxes that at the moment are drawn on the right of the chessboard (the ones that indicate the color to move) and choose between the two by using a multiple-choice widget such as the one that is used in Game->Save to choose the final result. This would also save space on the setup window.

I would like to add that one way to work around the problem with the White/Black button might be to prepare two corresponding png (or whatever other format) images and then insert them within the buttons, the same way the images of the pieces are inserted within the buttons in the right part of the same window. This would avoid the coloration of the button, which is the cause of the problem.
The second problem is also evident on my linux box. (debian over virtualbox)
Fixed now.
