uhm, this is really strange :/ i cant restore this error here, but maybe its also a problem with the os, not only the browser... hmm...
I think i have to say sorry for the moment, at first i need to add and change some more important parts of the page, so its hard to find the time But either way, i need to rewrite this beta-map completely (hopefully i will find the time this year *lol*), so i hope im able to fix it with the next big update :/

@ShatterWulf: Uffz... This is a very therapeutic info ;-)
