Discussion on Epicure - For Restaurants

I just found out, that the bug also depends on the window-size of the browser, if I decrease the window-size in ff just before the mobile-icon kicks in, the behavior changes: all active link-colors appear (contact as well) but than "About" is not working, and than the website jumps around 20px back and forth without touching it (every 5 to 10 sec) the whole time, there must be any incompatibility with some scripts, I guess...
