--- Comment #4 from Ken Sharp kennybobs@o2.co.uk 2009-06-02 14:02:49 --- It looks like the app picks up the fonts ok anyway, but you could try "winetricks corefonts" to see if it makes any difference.
Plus, does the console output anything that may be related? If there is a lot of text, just attach it to the bug. Thanks.
