Which version are you using ?
The newest version (1.0.0.23) uses a different render engine than the older ones, because of this it isn’‘t compatable with every system, Colin believes it DX related, while I’‘ve said it’'s an OpenGL problem.
Try the older version (1.0.0.20) instead, sorry I don’‘t have a d/l link as it’'s the even older 1.0.0.18 version we have in the archive here.
Thanks, the older version that’'s on the site here works for me
