I suggest including the following resources in /usr/share/texmf/xdvi/XDvi configuration file for improving the dialog box that comes up when no file name is specified: TransientShell*background: SlateBlue TransientShell*foreground: White TransientShell*Form.background: #c0c0c0 TransientShell*Form*Command.background: #c0c0c0 I could not find more resources to make the button shades better but this is much better than the plain default. Thanks
Fixed in CVS.
