Hi, I have seen the following, when clikling multiple times very fast on a link: Nav_open_url: new url='http://www.dwd.de/sid_520SLCXTTJJbtdSgR7JTsLGvkNt6TkS9ssWxDtLpSvVZtPCcyjPG!2071196629!214455508!1220728622349/bvbw/appmanager/bvbw/?_nfpb=true&_pageLabel=_dwdwww_wetter_warnungen_warnungen&T92053gsbDocumentPath=BEA__Navigation%2FWetter__Warnungen%2FWarnungen.html__nnn%3Dtrue&lastPageLabel=dwdwww_wetter_warnungen' Connecting to 141.38.3.62 DilloHtml(): content type: text/html; charset=UTF-8 *** [unknown] Assertion failed! *** anchor 'headline_color_324A92' not defined Aborted I tried www.dwd.de and then to click Wetter&Warnungen and the corresponding link. I have not looked into the source yet, but I think there is a ressource management problem. Greetings Andreas Kemnade
