thanks for your comment hugo. i really had no choice to blame the developers of geotheme, because i bought the theme and the support for it and i get no real response from them. they are repeati all te time that the support is done by the forum but they do not reply there as well.
thats what really annoys me.
anyway, i guess i found a solution for myself and i will try that at the weekend. can you tell me when bp1.7 will be released for germany (e.g. the german language file)?
